“…4 The current commercial generation of green light is obtained by using diverse laser light wavelengths to excite rare earth ions-doped phosphors. However, some defects of phosphors themselves restrict their application, such as poor water resistance, [5][6][7] opaqueness, 8,9 aging of the encapsulation material leading to a short life cycle and other shortcomings, 10 so there is an urgent demand for the development of a new light-emitting material that can overcome the aforementioned issues.…”

The Tb3+‐doped transparent glass ceramics containing Al4Ti2SiO12 crystal are synthesized by the melt‐solid‐crystallization method. The optimal heat treatment conditions for the glass ceramic samples are determined to be 750°C, 1.5 h based on differential scanning calorimeter, X‐ray diffractometer, scanning electron microscope, and light transmittance curve. The luminescence properties of the glass ceramics samples are characterized by a fluorescence spectrometer. The emission spectrum revealed that the dominant emission is green attributed to Tb3+, the optimal doping concentration is 0.3%. And the thermal quenching activation energy of 0.3% Tb3+‐doped glass ceramics is 0.2554 eV, while the relative sensitivity is 1.50% K−1 at 298 K and the absolute sensitivity is 2.27×10−2 K−1 at 418 K through variable temperature fluorescence spectroscopy test and a series of calculations. These findings demonstrate the excellent stability and temperature sensitivity of glass ceramics, thereby highlighting their potential for use in green lighting and temperature sensing applications.

“…Different host lattices such as vanadates [19], sulfides [20], phosphates [21], silicates [22], garnets [23], aluminates [24], molybdates [25,26], tungstates [27], nitrides [28], or oxynitrides [29] has been explored as a host lattice for RE ions for specific applications. Among all these, REdoped molybdate compounds have near-ultraviolet (UV) excitation, blue-green broadband emission, and good chemical and thermal stability, drawing attention to serving as excellent luminescent host phosphor [30][31][32]. In this work, we have chosen SrMoO 4 as our model host lattice.…”

The challenge of building a highly reliable contactless temperature probe with high sensitivity, good temperature-induced color discriminability, and economical synthesis has prompted the research community to work in the field of rare-earth-based luminescence thermometry. Moreover, the fast-growing market for optoelectronic devices has increased the demand for tunable color-emitting phosphors. In this study, Dy3+/Eu3+ co-doped SrMoO4 phosphors were developed as tunable color-emitting source and dual-mode luminescence thermometer. A facile and cost-effective auto-combustion method was used to synthesize the phosphors. Our work demonstrates a viable scheme for tailoring the emission of single-phase phosphors by precisely controlling the dopant concentrations and by modulating excitation wavelength. The overall emission is tuned from greenish-yellow to white and greenish-yellow to reddish-orange. A detailed energy transfer process from the host to the Ln3+ ions and between the Ln3+ ions is discussed. Further, anti-thermal quenching in the emission of Dy3+ ion is observed when excited with 297 nm. The dual-mode luminescence thermometry has been studied by analyzing the fluorescence intensity ratio of Dy3+ and Eu3+ ions upon excitation at 297 nm. The maximum relative sensitivity value for 4% Eu3+ co-doped SrMoO4:4%Dy3+ phosphor is 1.46% K−1 at 300 K. Furthermore, the configurational coordinate diagram is presented to elucidate the nature of temperature-dependent emission. Therefore, our research opens up new avenues for the development of color-tunable luminescent materials for various optoelectronic and temperature-sensing applications.

Exploring color tunable emission characteristics of Eu³⁺-doped La₂(MoO₄)₃ phosphors in the glass–ceramic form

Abstract: The glass–ceramic Eu-LMO-1050 is more suitable as a red-color-emitting phosphor material than the ceramic Eu-LMO-750. Further, Eu-LMO-1050 can overcome the problems related to the phosphor/silicone composite in commercial LEDs.
