摘要
In CuP the low temperature luminescence originates from eight transitions between a quartet (M = ±3/2, ±1/2) and a doublet (M’= ±1/2) with M and M’ denoting the (approximate) eigenvalues of the spin angular momentum Sz along the fourfold axis. Here we report (1) the selection rules governing the polarizations of the transitions; (2) the zero-field splitting ζ between the ±3/2 and ±1/2 components of the quartet for CuP in an n-octane crystal (ζ= 1.1 ±0.2 cm-1); (3) a photo-selection experiment on CuP in an isopentane glass from which it is concluded that the ratio of in-plane to out-of-plane polarization in the 0-0 band at 2.1 K amounts to an intensity ratio I∥/II⊥≈2. The implications of these results for the different SOC pathways are analysed. © 1979 Taylor & Francis Ltd.
