摘要

Photoluminescence properties of Ce~(3+) doped strontium haloborates synthesized by solution combustion technique were studied. Sr_2B_5O_9Cl:Ce~(3+) produce emission band peaking at 345 nm under 307 nm excitation radiation. Enhancement of luminescence intensity was observed when M~+ (Li~+, Na~+, K~+) ions were used as co-dopant in Sr_2B_5O_9Cl:Ce~(3+). Charge compensation by Na~+ ion in Sr_2B_5O_9Cl:Ce~(3+) show strongest luminescence intensity at 345 nm under 307 nm excitation radiation.
