Growth conditions for wurtzite zinc oxide films in aqueous solutions

A pH above 9.0 was essential for the formation of wurtzite zinc oxide (ZnO) in aqueous solution systems.The addition of complexing agents to decrease the deposition rate was required for the direct growth of ZnOon the surface of substrates through heterogeneous nucleation. The nucleation of the crystals was promoted byundercoats derived from zinc acetate. Wurtzite Zn..
