Glass having a uniform, good transparency, good chemical stability, and isotropic characteristics, easy to prepare a variety of different sizes and shapes of products, such as fibers and other shaped articles, and large-size products. The glass may be doped with a high concentration of rare earth ions, the glass material is good matrix material for the preparation of optical materials. Special 4f electron structure of rare earth ions, it has excellent fluorescence properties, such as light emitting pure color, stability, conversion efficiency and high physical and chemical properties. Soda lime silicate glass is the most common but also the most extensive use of a glass material, mainly used in the fields of construction, automotive, decorative, lighting, photoelectric and cheap raw materials used, the preparation process is mature, so the study of rare earth ions The light emission in the soda lime silicate glass is of practical significance. Through the preparation of a series of glass samples, absorption, excitation and emission spectra characterized the spectroscopic properties of the rare-earth ion doped The fluorescence properties of soda-lime-silica glass doped with different concentrations of Eu3, Sb3 fluorescence properties of Eu3, alkaline earth metal and alkali metal oxide to replace the fluorescence properties of Eu3, B203 to replace the same amount Si02 fluorescence properties of Eu3 and The Dy3 the light sensitizing effect on Eu3; Sm3 single blending Sm3, Ce3 co-doped fluorescent properties; Tb3-doped glass and glass spectral properties. . Absorption spectra of Eu3 in sodium calcium silicate matrix glass, excitation spectra, emission spectra, and vest in the corresponding energy level transitions doped glass can absorb ultraviolet light and visible light emitted orange-red shade. The doping concentration within the range of 0-1.0mo1% was not observed the phenomenon of concentration quenching. When codoped when Sb3 with Eu3-, Sb3 to a certain extent can be absorbed part of the energy is passed to the of Eu3 obtained, and with the Sb3 / Eu3 ratio increases the higher the efficiency of sensitized emission. Two different alkali metal oxide partially replace Na2O on Eu3 doping the fluorescence intensity of the soda lime silicate glass of Li, K Na order enhance the fluorescence intensity of the soda lime silicate glass; different alkaline earth metal oxide is doped on Eu3 Press of Sr2 Ca2, Mg2 order in an ascending order. Moderate B203 same amount to replace Si02 found Eu2 emission peaks in the blue region, description of the Eu3 and Eu2 two ions, at the same time, and improve the the the Eu3-Eu2 conversion efficiency as the ratio of the increase of the B203/SiO2 infrared spectroscopy outside, but also part of the energy transfer to Eu3 sensitized luminous, when Eu3 / Dy3 both the concentration ratio of 1:2, sensitized the best. , Co-doped with 394nm excitation emission system appear blue, yellow, red emission, the relative strength of the three can adjust the concentration ratio of about 1:1.5:2.3, composite emit a variety of colors. 5. Sm3 the absorption spectrum in the matrix glass of sodium calcium silicate, excitation spectra, emission spectra, attribution of the corresponding level transition. Analysis of the influence of the doping the Sm3 ion concentration on the fluorescence intensity, determine the the Sm3 optimum doping concentration in the glass matrix 0.8mo1%. Ce3 - and Sm3 codoped matrix glass in the spectral properties, the energy transfer mechanism of the two rare earth ions in the matrix glass may. The study found good results, Ce3 of Sm3 sensitized play. 6. Tb3 sodium calcium silicate matrix glass and glass in the excitation spectrum, emission spectrum, to vest the corresponding energy level transitions; discussed the impact of doping the Tb3 ion concentration on the fluorescence intensity. The study showed that the concentration quenching effect in the glass matrix, with the heat treatment is carried out, the internal energy transfer between Tb3 ions, the blue region of the emission weakening characteristic emission of green area to strengthen.
