%X Using photoluminescence (PL) and Raman scattering (RS), the MBE grown Hg 1- x Cd x Te ( x =0.325) epilayers were studied. The PL measurement shows a strong near band emission peak with a FWHM of 5meV, which indicates high crystal quality obtained. Three peaks, the relatively strong HgTe like TO mode at 119cm -1 and HgTe like LO at 139cm -1 and a weak LA mode at 93cm -1 , were observed on RS spectra. The weak peak at 93cm -1 has not been reported previously. The assignment of the peak is based on the comparison with the result of far infrared transmittance spectra(FIT).
