摘要：
(GaN)(1-x)(ZnO)(x) solid solution with hexagonal plate-like morphology was synthesized by the nitridation of Zn/Ga/CO3 layer double hydroxides (LDHs) precursors, which were obtained by a co-precipitation method. Structure and composition evolution that depends on temperature during the nitridation between 500 and 900 degrees C were studied to reveal the transformation procedure from LDHs to (GaN)(1-x)(ZnO)(x) solid solution. The LDHs transformed to wurtzite structure (GaN)(1-x)(ZnO)(x) solid solution after a short time nitridation and maintained the hexagonal morphology until the temperature raised to 900 degrees C. EDX analysis revealed that the Ga/N ratio is more close to 1 when the temperature increased, and the Zn/Ga ratio decreased due to the volatilization of zinc. The diffuse reflection spectra for the samples obtained at different nitridation temperatures indicated that the light absorption properties of samples were closely related to the Ga/N and Ga/Zn ratios.
