CdS,Se,Zn powder and glass matrix were used as raw material to prepare the CdS_xSe_(1-x) quantum dots silicate glass by using co-melting method. The effect of ZnO content on the microscopic structure and luminescent properties of CdS_xSe_(1-x) quantum dots silicate glass were studied. Experimental results indicate that Zn O can significantly influence the luminescence properties of CdS_xSe_(1-x) quantum dots glass. The results of ultraviolet-visible absorption spectrum and fluorescence spectrum analysis show that the CdS_xSe_(1-x) quantum dots are in a strong confined area,which lead to a strong belt edge exciton emission phenomenon,proving that the quantum size effect of quantum dots is obvious under the excitation of 470 nm blue light. When the mole fraction of ZnO is 13%,the PL spectrum peak is the strongest,and the half width of peak is the narrowest.
