Using solution-melt method two single crystals, (Ga₇₀La₃₀)₂S₃₀₀, (Ga_{69.75}La_{29.75}Er_{0.5})₂S₃₀₀, were grown. The maxima of the luminescent radiation in the photoluminescence spectrum of the (Ga_{69.75}La_{29.75}Er_{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).
