摘　　要：根据GaP∶N（Te）的光致发光和喇曼光谱,提出了GaP∶N发光中的光学声子双伴线可能分别由LO^г和它的束缚态LO_XN^г对所产生的初步设想.另外,尝试对Te的声学声子翼中所含的组合声子作出判别.According to the Raman spectra and photoluminescence for GaP:N (Te), a pre-liminary consideration to the formation of double phonon replica is discussed. It issuggested that the doublet-linesis discussed.It is suggested that the doublet-lines.relating to the optical phonons may be originated from LO~Γ and its bound stateLO_(X,N)~Γ on nitrogen isoelectronic traps respectively. Besides, attempts have been madeto find out the individual acoustic phonons included in the phonon-combinations whi-ch result in the phonon-wings discovered recently.
