Abstract: The electrical conductivity of P-doped ZnO can be controlled by changing the P-doping concentration. With increasing P concentration, ZnO can be changed from n type to p type. At the same time, a redshift of the band gap energy is observed by using the photoluminescence spectroscopy and UV-visible spectrophotometer. X-ray diffraction results show that lattice spacings of ZnO increase with P concentration, which indicates that P substitutes O, and this leads to a lattice spacing increase and an optical band gap energy decrease. © 2006 American Institute of Physics.
