Using solution-melt method two single crystals, (Ga₇₀La₃₀)₂S₃₀₀, (Ga_69.75La_29.75Er_0.5)₂S₃₀₀, were grown. The maxima of the luminescent radiation in the photoluminescence spectrum of the (Ga_69.75La_29.75Er_0.5)₂S₃₀₀ single crystal correspond to the intracentric transitions in the erbium ions: ²H_11/2 → ⁴I_15/2 (525 nm) and ⁴S_3/2 → ⁴I_15/2 (545 nm).
