Abstract: A series of Gallium-substituted Cerium-doped yttrium aluminum garnet (YAGG:Ce) phosphors were produced by co-precipitation. The formation process and structure of the Ga3+-substituted phosphor powders are characterized by TG, FTIR, XRD and XPS, and the impacts of Ga3+ concentration on the luminescence properties have been investigated. The results show that the blue shift occurs after Ga3+ replaces Al3+ in matrix, and the intensity of emission spectrum is affected by the concentration of Ga3+.

Key words: rare earth; co-precipitation method; YAG; spectral properties
