Abstract

Tb3+ doped LaB3O6 phosphors with various dopant concentrations are synthesized via the combustion technique.

X-ray diffraction patterns showed that both undoped and Tb3+ doped LaB3O6 samples matched PAN-ICSD

reference. Scanning electron microscope scans indicated random aggregation. To identify the TL features, TL

glow curves of Tb3+ doped LaB3O6 samples at various dopant concentrations are investigated by using different

optical detection filter combinations. LaB3O6:Tb3+ (5.0%) and IRSL-TL 565 nm are chosen as the most suitable

sample and ideal detection filter combination. Following the preheating experiments, the TL maximum is noted

at a temperature of around 265 ◦C with a heating rate of 2 ◦Cs
