“…An effective approach to manufacture superior scintillators is developing transparent glass‐ceramics (GC) in which fluoride nanocrystals are embedded in the oxide glass matrix. The oxyfluoride GC samples not only possess lower phonon energy related to the fluoride nanocrystals, but also have good mechanical and chemical stability related to the oxide glass matrix . In brief, compared to crystals and ceramic scintillators, GC scintillators for X‐ray detections possess excellent luminescent and XEL properties from nanocrystals, and maintain the good stability and elaboration superiorities of glass.…”

“…It hints the Li 2 SrSiO 4 :4%Tb 3+ phosphor has a good thermal quenching effect with respect to Ca 3 Si 2 O 7 :Tb 3+ green phosphors . The activation energy ( E a ) can be calculated for the optimized phosphor by Arrhenius equation as follows: ;lnI0I=lnAEakT…”

“…Since FIR is independent of the fluorescence loss and fluctuation under excitation, the temperature dependence of the measurement conditions can be negligible. As the groundwork of many temperature‐sensitive optical devices, the FIR technique takes advantage of two adjacent thermally coupled energy levels (TCELs) of rare earth ions . Thanks to the wide choice of temperature range, flexible device structures and controllable energy levels, the FIR based non‐contact temperature sensor is regarded as a promising option for optical thermometry .…”
