Specific features of the solid-phase synthesis of Sr{sub 1-x}Eu{sub x}B{sub 4}O{sub 7} (x 0-0.15) in air are studied. The photo- and thermally stimulated luminescence of Sr{sub 1-x}Eu{sub x}B{sub 4}O{sub 7} is investigated in the range of Eu content 0.01 < x < 0.15. The main energy parameters of traps are determined. It is shown that the peak of thermally stimulated luminescence at T = 380 K can be related to the decomposition and radiative relaxation of the [Eu{sup 3+}{sub Sr{sup 2}{sup +}} F{sup +} center] pair.
