“…The present work was then undertaken with the object of scrutinizing further the structure–property relationship in Nd 3+ -containing phosphate glasses. Barium phosphate was chosen as the glass host matrix since large-radius Ba 2+ cations are generally considered suitable network modifiers for achieving necessary optical, thermal, and mechanical properties in phosphate glasses for various photonic applications. ,,,− Hence, using as a starting point, the 50P 2 O 5 -50BaO glass matrix prior considered by the author, ,, the glasses were made with 50P 2 O 5 -(50 – x )BaO- x Nd 2 O 3 (0 ≤ x ≤ 4 mol %) nominal compositions by the melt-quenching technique. A comprehensive experimental investigation followed, encompassing measurements by densitometry, X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), dilatometry, UV–vis–NIR optical absorption, and photoluminescence (PL) spectroscopy with decay kinetics assessment.…”

“…Glasses activated with near-infrared (NIR)-emitting Nd 3+ ( f 3 ) ions have been the subject of extensive research, given their use in high-power lasers − and more recently being interesting in the context of solar spectral converters. − Among the numerous glass matrices available, phosphate-based glasses are particularly attractive, given their high metal solubility, suitable thermal properties (e.g., low-melting character), and associated low production costs and manufacturability. − Studying the composition–structure–property relationship in this type of glass systems is thus of interest from fundamental and applied perspectives.…”

Near-infrared (NIR)-emitting phosphate glasses containing Nd 3+ ions are attractive for applications in laser materials and solar spectral converters. The composition− structure−property relation in this type of glass system is thus of interest from fundamental and applied perspectives. In this work, Nd 3+ -containing glasses were made by melting with 50P 2 O 5 -(50 − x)BaO-xNd 2 O 3 (x = 0, 0.5, 1.0, 2.0, 3.0, 4.0 mol %) nominal compositions and studied comprehensively by density and related physical properties, X-ray diffraction (XRD), Raman spectroscopy, O 1s X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), dilatometry, ultraviolet−visible (UV−vis)−NIR optical absorption, and photoluminescence (PL) spectroscopy with decay dynamics assessment. The densities and molar volumes of the Nd 3+ -containing glasses generally increased with Nd 2 O 3 concentration also resulting in shorter Nd 3+ −Nd 3+ distances. XRD supported the amorphous nature of the glasses, whereas the Raman spectra evolution was indicative of glass depolymerization being induced by Nd 3+ ions. Oxygen (1s) and phosphorus (2p) analysis by XPS for the glass with 4.0 mol % Nd 2 O 3 agreed with the increase in nonbridging oxygens relative to the undoped host. DSC results showed that the glass transition temperatures increased with Nd 3+ concentration, with the glasses also displaying a decreased tendency toward crystallization. Dilatometry showed trends of increasing softening temperatures and decreasing thermal expansion coefficients with increasing Nd 2 O 3 content. A glass strengthening/tightening effect was then indicated to be induced by Nd 3+ with higher field strength compared to Ba 2+ ions. The UV−vis−NIR absorption by Nd 3+ ions increased consistently with Nd 3+ concentration. The UV−vis absorption edges of the Nd-containing glasses were also analyzed via Tauc and Urbach plots for comparison with the undoped host. Concerning the PL behavior, the Nd 3+ NIR emission intensity was highest for 1.0 mol % Nd 2 O 3 and decreased thereafter. The decay kinetics of the 4 F 3/2 emitting state in Nd 3+ ions analyzed revealed decreasing lifetimes where the decay rate analysis pointed to the prevalence of ion−ion excitation migration leading to PL quenching at high Nd 3+ concentrations.

“…The study of doped glasses currently attracts attention in solar energy conversion and some new concepts and techniques have recently been suggested. [67][68][69][70][71] The vision of the present study is to utilize intense charge transfer absorption bands of TM ions for solar light absorption with the consequent efficient energy transfer to co-doped lanthanide ions with the downshied emission at an energy appropriate for a solar cell. Herein, the rst step in this direction has required the experimental investigation of TM ion-doped glasses and the interpretation of the spectra obtained.…”

“…Neodymium-doped glasses have been studied extensively, given their near-infrared (NIR) emission useful for high-power lasers − and attractive for solar spectral converters. − Seeking to boost the emission from the Nd 3+ ( f 3 ) ions valuable for applications, the codoping of the glasses with different ions intended to act as sensitizers has been proposed, which includes Mn 2+ , , Cr 3+ , Sn 2+ , Cu + , , and Ag + . , Among these, the use of the red-emitting Mn 2+ ions is particularly interesting, given the potential to be used in conjunction with NIR-emitting rare earth in glasses to be exploited for solar cell applications …”

This work reports on various properties and analysis of optical interactions in phosphate glasses containing redemitting Mn 2+ and near-infrared (NIR)-emitting Nd 3+ ions, which are of interest for energy applications and solar spectral converters. The glasses were made by melting with 50P 2 O 5 −(48 − x)BaO−2MnO−xNd 2 O 3 (x = 0, 0.5, 1.0, and 2.0 mol %) nominal compositions and characterized by X-ray diffraction, density and related physical properties, differential scanning calorimetry, dilatometry, UV−vis−NIR optical absorption, and photoluminescence spectroscopy with decay kinetics analysis. The glasses were X-ray amorphous, wherein the physical and thermal properties of the Mn 2+ /Nd 3+ -codoped glasses were largely impacted by Nd 2 O 3 contents. The optical absorption spectra supported the occurrence of Mn 2+ ions and the lack of Mn 3+ in the codoped glasses, while the absorption due to Nd 3+ ions increased steadily with Nd 2 O 3 contents. Analyzing the glass absorption edges via Tauc and Urbach plots was further pursued for a comparison. The photoluminescence evaluation showed a consistent suppression of the emission from Mn 2+ ions with increasing Nd 3+ concentration, while the decay kinetics revealed shorter lifetimes in connection with increased Mn 2+ → Nd 3+ transfer efficiencies. Excitation of Mn 2+ at 410 nm, however, led to the Nd 3+ NIR emission being most intense for 1.0 mol % Nd 2 O 3 , despite the 4 F 3/2 emission decay analysis showing lifetime shortening throughout. Considering the compromise between red and NIR emissions, the Mn-containing glass doped with 0.5 mol % Nd 2 O 3 is put in perspective with the concept of solar spectral conversion.
