Abstract:Samarium ion (Sm3+)‐doped alkali zinc alumino borosilicate (AZABS) glass was synthesized via quick melt quench technique. Various spectroscopic studies like optical absorption, photoluminescence (PL) emission, PL excitation, temperature‐dependent PL and PL decay kinetics were performed on the as prepared glass system. Under 402 nm excitation, three sharp bands at wavelengths 563, 599 and 645 nm corresponding to transitions 4G5/2 → 6H5/2, 6H7/2 and 6H9/2, respectively, can be seen in the PL emission spectra.

“…[7][8][9][10] Thermal quenching (TQ) is caused by the anabatic non-radiative relaxation of electrons from the excited state to the ground state at high working temperature. [11][12][13][14] It shortens the service lifetime of pc-WLED devices and restrains the widespread use of phosphors. Hence, it is necessary to explore luminescent materials with excellent thermal stability.…”
The design of thermostable phosphor is still a pivotal challenge in pc-WLED applications. Herein, an efficient strategy is proposed to design excellent thermostable red emission in singly Mn2+-doped near zero...
