This work gives description of method receiving powder titanium oxide doped ions samarium (TiO2:Sm3+) with pure anatase structure. Synthesized sample has strong red-orange luminescent lines under exposition of ultraviolet radiation. Critical role of charge carriers photogenerated in titanium oxide host under radiation for mechanism luminescence origins has been identified. Kinetic curves of photoluminescence TiO2:Sm3+ demonstrate typical character for phosphors which recombination processes are realized in intracenter luminescence.
