Preparation, characterization and room temperature photoluminescence properties of a zinc oxide nanosheet network grown on glass substrate by a facile chemical route

► Zn(AC)2·2H2O solution and cetyltrimethyl ammonium bromide as precursors. ► Hydrothermal method prepares ultralong and ultrathin zinc oxide nanosheet network. ► Zinc oxide nanosheet network has a high crystalline hexagonal wurtzite ZnO structure. ► Zinc oxide nanosheet network displays room temperature photoluminescence at blue and green emissions.
