摘      要：screw-cone-like Zn_(2)GeO_(4)-ZnO particles with a base diameter of approximately 400 nm and a height of 400–800 nm or so were successfully synthesised by combustion oxidation of zinc and germanium powder at 960℃.No catalyst or carrier gases were *** and SEM analyses reveal that Zn_(2)GeO_(4) and ZnO grew to parasitic crystals evenly in interaction with each *** images exhibit the homogeneity of the distribution of Ge and *** formation mechanism is discussed and attributed to the unique growth process of the screw-cone-like Zn_(2)GeO_(4)-ZnO particles and its vapour-solid(VS)growth *** addition,the Zn_(2)GeO_(4)-ZnO particles could tune the energy level structure of nano-tetrapod ZnO,which leads to the emission peak redshift from 376 nm to 435 nm and enhances the light emission intensity in the visible light region.
