Preparation and Luminescence Properties of ZnO-SiO2-B2O3-Na2O:Sm3+ Glass

The 40ZnO-30SiO(2)-20B(2)O(3)-10Na(2)O:Sm3+ glass was prepared by high-temperature melting method. The structure and composition of the glass matrix was investigated by Infrared spectrum (IR). The absorption, excitation and emission spectra of the samples were tested, and the results showed that the glass can emit orange shade under light excitation. The emission peaks at 565nm, 604nm and 650nm wavelength were corresponding to the (4)G(5/2)-> H-6(5/2), (4)G(5/2)-> H-6(7/2) and (4)G(5/2)-> H-6(9/2) transition emission of Sm3+, while the (4)G(5/2)-> H-6(7/2) transition emission was the strongest. So the best Sm3+-doping molar concentration was 0.4%. The spectroscopic properties indicated that 40ZnO-30SiO(2)-20B(2)O(3)-10Na(2)O: Sm3+ was expected to become a new conversion material.
