Effect of N and P codoping on ZnO properties
Nitrogen and Phosphorus co-doped (N+P)-zinc oxide (ZnO) films were RF sputtered on coming glass substrates at 350 ℃ and comparatively studied with undoped,N-,and P-doped ZnO.X-ray diffraction spectra confirmed that the ZnO structure with a preferred orientation along <002> direction.Scanning electron microscope analysis showed different microstructure for the N+P co-doping,and thus probably confirming the co-existence of both the dopants.X-ray photoelectron spectroscopy spectra revealed that the chemical composition in N+P co-doped ZnO are different from that found in undoped,N-,and P-doped ZnO.The atomic ratio of N and P in N+P co-doped ZnO is higher than that in single N or P doped ZnO.One broad ZnO emission peak around 420 nm is observed in photoluminescence spectra.The relative intensity of the strongest peak obtained from co-doped ZnO films is about twice than the P-doped and thrice than the pure and N-doped films.
