Synergistic effects of Tb doping in long-persistent luminescence in CaGaO: xBi, yZn phosphors: Implications for novel phosphorescent materials.

Long afterglow phosphors constitute an emerging class of compounds with wide application in several fields, from photonic to dosimetry, solar energy storage and photocatalysis. In this study, we synthesized and thoroughly characterized a new class of persistent emitting materials, CaGaO: xBi, yZn, zTb. Through the utilization of X-ray and Raman spectroscopy, as well as optical measurements including static and time-resolved luminescence, thermoluminescence, and phosphorescence, the effects of the Tb concentration on the optical and structural properties of the material has been deeply studied.
