Abstract：The growth and harvest of crops are closely related to photosynthesis and plants have strong absorption of red and blue light, in which red light has helminthic function. So it is very meaningful to transform the rest light in the vertical element of sunlight into red and blue light. The authors can simulate artificial light enviro nment in order to develop green agriculture and increase production of plants. As we all know, rare-earth doped Eu3+glass materials have wavelength conversion function. Based on the two views of the above, in this paper, the authors have prepared doped Eu3+cadmium aluminium silicate glasses by high temperature solid-state reaction method. The absorption spectra, excitation spectra, emission spectra are obtained by experiment at room temperature, in which have strong red and blue emissions. Gain the best concentration of doping corresponding to the strongest absorption peak. The charge-transfer band (CT band)is moved to 320 nm (red shift)due to the addition of Cd2+. By changing alkali metal ions, we can adjust and mix different intensity of blue light according to the demand. Based on J-O theory, we can gain the structure order of samples by calculating intensity parameter Ω2 and Ω4.
