“…The differential equations are solved simultaneously for excitation stage, relaxation stage and the TL read-out stage. This method was employed by Amirouche Bouremani et al to explain concentration quenching in SrY 2 O 4 :Eu 3+ phosphors [25]. As it is not the scope of our study, we have not focused on the mechanism of concentration quenching.…”

This article explores the structural, morphological, thermoluminescence, and temperature-dependent emission properties of novel Dy3+ doped BaMgAl10O17(BAM-Dy) phosphors. Structural studies reveal that the phosphor has a similar structure to β-alumina. Rod-shaped interlinked surface morphology is a notable characteristic of the BAM-Dy samples. Incorporation of Dy3+ ions lead to the formation of distinct emission peaks (485 nm, 577 nm, and 635 nm) in the PL emission spectra. The effect of dopant concentration on the light output is crucial, and the highest PL intensity is observed for 1.5 mol% of Dy3+ concentration. The potential use of BAM-Dy phosphors for Gamma radiation detection and measurement is tested through thermoluminescence studies, which reveal high sensitivity, low threshold dose values, and exceptional response to low gamma doses, making them suitable for dosimetry applications. The investigation of trap parameters provides useful information about the number of traps, trapping mechanism, and trap energies, which is essential for in-depth study of synthesized phosphors for γ dosimetry application. The study of the effect of temperature on the luminescence behaviour is crucial for the application of phosphors in the light-emitting field. The BAM-Dy samples exhibit excellent thermal stability even at 210 °C, making them suitable for use in the field of White LEDs.

“…6 Hence, combining soft synthetic conditions with high crystallinity to obtain Eu III -activated bright red-emitting phosphors is highly desirable. Thus, the SrY 2 O 4 :Eu III red phophor 7,8 is an ideal candidate in this context, having been synthesized by an adapted Pechini route and recently reported by us, 9 exhibiting high (480%) intrinsic quantum yield under near-UV excitation.…”
