A STUDY OF PHOTOLUMINESCENCE OF GaP(N,Te,Zn) UNDER HIGH PRESSURES
GaP(N,Te,Zn)的静压光致荧光研究

The photoluminescences of GaP (N, Te, Zn) at 77 K have been studied under high pressures. The pressure coefficients of donor Te and exciton levels bound to N, NN1, NN3, and neutral donor Te have been obtained. The pressure behaviors of these levels have been discussed. The zero-phonon line of free excitons in GaP is observed for the first time.
