“…A possible nonradiative pathway is the conduction band of the host LSO. 35,37 The proposed Ce2 5d to conduction band energy distances correlate with the measured Ce2 PL quenching activation energies reported in Table II. This places the higher energy 5d levels above the conduction band which could possibly quench their emission.…”

The effect of cerium concentration on single crystal lutetium orthosilicate (Lu 2 SiO5, LSO) was investigated with temperature-dependent steady state and time resolved luminescence spectroscopy. The results were used to determine the thermal quenching activation energies and the phonon energies responsible for the thermal broadening of the luminescence spectra. The measured phonon values were used to calculate configuration coordinate (CC) diagrams of the luminescence centers. The nature of single crystal LSO:Ce concentration quenching was determined to be due to radiative energy transfer by self-absorption. The observed broadening of the excitation spectra and narrowing of the emission spectra with increasing cerium was explained via a CC model. A combination of the CC model and concentration quenching explained the measured thermal quenching activation energies.

“…The emission spectra presented in paper [19] show the significant changes of the emission lineshape at higher pressure range, whereas results presented in [24], that contains data for pressure lower than 40 kbar, do not show the significant changes in emission lineshape. It is possible that for pressure above 40 kbar we deal here with the structural transformation similar like in LiSc(WO 4 ) 2 Cr 3+ [38] and in YAlO 3 :Ti 3+ .…”

Visualized self-powering stress sensing can be realized via mechanoluminescence (ML) materials due to their ability to convert mechanical stimulate into optical signals. Traditional ML-intensity-based stress-sensing is susceptible to errors caused by unpredictable measurement circumstances, which can be significantly improved by a recently developed ratiometric ML sensing strategy. Herein, a series of dual-activator phosphatic materials are designed to realize ratiometric ML. The linear dependence of mechanoluminescence intensity ratio (MLIR) on the applied force leads to an obvious variation in ML emission color upon different applied stress, and therefore enables a colorresolved visualization of stress-sensing. Specifically, an evaluating system is established to quantify the stress-sensing performance of ratiometric ML materials for the first time, which is considered to be an important step toward the practical application of ratiometric ML-based stress-sensing.
