- •
(Sr,Ca,Ba)2SnO4:La,Sm were prepared by solid-state reactions.
- •
ML and PL spectra, and thermoluminescence properties were investigated.
- •
Emission ascribe to the 4G5/2 to 6HJ (J = 5/2, 7/2, 9/2, 11/2) transitions of Sm3+.
- •
Traps are tuned in both trap depth and quantity.
- •
Traps are ameliorated in both trap depth and quantity by Ca2+ and Ba2+ substitution for Sr2+ and La3+ co-doping with Sm3+.
