“…Rare earth (RE 3+ ) ion‐doped materials play crucial functions as active ions in a wide range of modern optical materials and utilized in photonic devices such as LEDs, solar cells, semiconductor devices, laser cooling, solid‐state lighting (SSL) devices, fibre amplifiers, lighting and display technology, and memory devices [1–8]. Owing to their lasing activity in the ultraviolet, visible and near‐infrared (NIR) spectra, RE 3+ ion‐doped glass are particularly valuable materials for laser emission in SSL [4, 5].…”

Different concentrations of Sm2O3 doped lead borosilicate glasses were synthesized by using the method melt quenching and their characteristics were analyze using X‐ray diffraction (XRD), Fourier transform infrared (FTIR), absorption, emission, and decay curves. From the XRD, it has been confirmed the non‐crystalline nature of titled glasses. The structural groups that were existing in the host glass have been discovered by looking at the FTIR spectrum. The Judd‐Ofelt (JO) intensity parameters and oscillator strengths are derived from the absorption spectra and compared to with various reported systems. The excited luminescent levels of the Sm3+ ion's radiative properties are further computed using the JO intensity parameters. Effective bandwidth, emission cross‐sections (σe), and several lasing properties are assessed from emission spectra and compared to other reported glass system. The decay curves of 4G5/2 level of Sm3+ ion has also been measured and examined. Additionally, the color coordinates of the CIE (Commission International de I'Eclairage) chromaticity were assessed. The titled glasses were suited for visible reddish‐orange luminescence devices based on all obtained parameters.

“…B ions form the hosting glass matrix as a combination of coordinated-trigonal and tetrahedral units via oxygen ions [25][26][27]. In neodemium bismuth borate system of glasses, B 2 O 3 combines with Nd 2 O 3 and Bi 2 O 3 and form a glass structure of electron poor and electron rich atoms [28].…”

Neodymium strontium bismuth borate glass samples were prepared using the traditional technique of high-temperature melting. The optical absorption spectra of the studied samples were recorded at room temperature. Analyzing the recorded spectra, important optical parameters were determined; for example, refractive index, optical dielectric constant, the indirect optical band gap and Urbach energy. The calculated Judd-Ofelt parameters exhibited trend which is Ω 2 >Ω 6 >Ω 4 . Moreover, the experimental and calculated oscillator strengths f , exp f cal of the radiative 4f transitions, their lifetimes τ, refractive indices n, the emission, absorption cross sections ( ) s l , abs ( ) s l emis and the branching ratio β were all determined and investigated. Calculations of the optical gain coefficient ( ) l G for all emission peaks revealed the possibility to use the present glass in laser emission materials and optical communication applications.

“…The significance of this research work underlies white light emission through co‐doping that is heavily reliant on energy transfer processes linked between RE ions. Efficient fluorescence of yellow and blue, reddish orange, and green from dysprosium, samarium, and erbium ions detailed in various reported works [ 3–5 ] predicts a combination of these ions in a single host as an active contender for white light emission from luminescent glass. Few works have revealed that energy transfer mechanisms take place between Dy–Sm, Sm–Er, and Dy–Er ions in different glass materials.…”

A series of Dy3+/Sm3+/Er3+ triply doped multicomponent borosilicate glasses (DSE) was synthesized using varying Er3+ ions concentrations through a conventional melt quenching technique. The influence of triple doping on the optical characteristics of the prepared glass was evaluated to estimate the possibility of achieving white light emission through optical absorption, photoluminescence excitation (PLE), and emission (PL) measurements. Based on the PLE and PL spectral profiles, the presence of energy transfer processes between Dy3+, Sm3+, and Er3+ was confirmed. Furthermore, for Dy3+/Sm3+/Er3+ triply doped glass, an enhancement in Er3+ green luminescence and a noticeable decrease in Dy3+ and Sm3+ emissions were detected with the increase in Er3+concentration. The nature of energy transfer in DSE glass was investigated through Dexter's energy transfer mechanisms and the obtained result suggested that a dipole–dipole interaction was responsible for the dominant Sm3+ to Dy3+ and Dy3+ to Er3+ energy transfer processes. The precise characteristic colours that emanated from the as‐prepared samples were evaluated using Commission Internationale de l'Éclairage co‐ordinates and correlated colour temperature values and suggested its suitability for white light emission. The quantum efficiency of the prepared glass was determined experimentally. The aforementioned results recommend that the Dy3+/Sm3+/Er3+ triply doped multicomponent borosilicate glass irradiated with ultraviolet light sources might be useful for the generation of cool/warm white light‐emitting applications.
