The P Kβ emission spectra in fluorescence from ZrP, NbP, MoP, HfP, TaP, WP, AgP_2, CdP_2, Mn_3P_2, Cd_3P_2 and GaAs1-xP_xfor 0.2 ≤ x ≤ 1 are measured with a high-resolutiontwo-crystal vacuum spectrometer equipped with Ge(111) crystals. Theinfluence of metal atoms appears distinctly in the P Kβemission spectra of transition-metal phosphides. The effect ofarsenic atoms appears slightly in the P Kβ emission spectraof GaAs1-xP_x. The P Kβ emission spectra of AgP_2, CdP_2, Cd_3P_2 and GaAs0.6 P0.4 are compared withavailable P L2, 3 emission and XPS valence-band spectra ona common energy scale. It is shown that the P 3p electronsinteract fairly with the metal d electrons in the upper partof the valence band for MP (M = Zr, Nb, Mo, Hf, Ta, W) and Mn_3P_2;considerable p-d, s mixing occurs in the middle part for AgP_2and in the lower part for CdP_2 and Cd_3P_2; and the Ga 3dstates mix fairly with the P 3s states in GaAs0.6P0.4.
