Micro-Raman spectra of four annealing Cd1-yZnyTe crystal samples with small concentrations were measured within the spectral range of 40cm-1 to 500cm-1. Three main Raman scattering peaks were found in all four samples and that the Raman peaks in the samples get higher and narrower with longer annealing time. Strong photoluminescence in the four samples also were observed, which come from the band edge radiation. The composition value y of Cd1-yZnyTe crystals can be easily calculated by using these micro-photoluminescence peaks.
