FIG. 1.

PL spectra at of undoped and P-doped ZnO, showing the existence of a violet luminescence band at in the P-doped sample.

FIG. 2.

(a) Integrated intensity of the transition as a function of the laser excitation intensity. The triangles are the experimental data points and the solid line is the fit using a power law. (b) Energy shift of the transition as a function of the excitation intensity. (c) Power dependence of the transition on the phosphorus concentration. The triangles are experimental data points and the solid line is the fit using a power law.

FIG. 3.

Temperature dependent measurement of the integrated intensity of the DA transition.

FIG. 4.

Evolution of the luminescence of P-doped ZnO as a function of the annealing temperature . The violet band is entirely quenched at .

Tables
