【摘要】：能源短缺和环境污染越来越制约着社会的可持续发展,而太阳能光伏发电因其具有良好的可持续发展性,目前已成为人类能源结构的关键组成部分。所以如何更有效的利用太阳能光伏发电已成为目前国内外研究的热点。由于稀土离子具有多能级特性,在激发光源的激发下产生上转换或下转换发光。利用这种发光特性,可将太阳能电池半导体材料不能够响应的光能转换为可利用的能量,从而提高太阳能的利用率。故稀土掺杂硅酸盐玻璃在太阳能光伏电池中有着潜在的实际应用价值。稀土发光玻璃材料在制备过程中需要有性能良好的玻璃材料为基质,以往大部分的研究,基质玻璃材料大多以氟氧玻璃、微晶材料以及玻璃陶瓷等为主,至于机械性能强,化学性能稳定好的硅酸盐玻璃则相对少见。本文通过高温熔融法实现对稀土Ce~(3+)/Sm~(3+)/Eu~(3+)离子掺杂硅酸盐玻璃的制备,获得发光玻璃样品。并采用紫外-可见-红外分光光度计测试玻璃样品的透过率曲线、荧光分光光度计分析玻璃样品的激发光谱和发射光谱、以及采用XRD图谱表征发光玻璃样品的玻璃态。通过对稀土Ce~(3+)/Sm~(3+)/Eu~(3+)离子单掺及双掺玻璃样品的一系列性能表征及光谱测试,结果表明了稀土Ce~(3+)/Sm~(3+)/Eu~(3+)离子单掺及双掺的硅酸盐玻璃均可吸收半导体不响应的紫外光,并通过下转换作用发射出可见光的良好发光性能。
[Abstract]:Energy shortage and environmental pollution are increasingly restricting the sustainable development of society. Solar photovoltaic power generation has become a key component of human energy structure because of its good sustainable development. Therefore, how to make more effective use of solar photovoltaic power generation has become a hot spot at home and abroad. Because rare earth ions have multi-level characteristics, upconversion or downconversion luminescence is produced under excitation of excitation light source. Using this luminescent property, the light energy of solar cell semiconductor material can be converted into available energy, and the utilization rate of solar energy can be improved. So rare earth doped silicate glass has potential application value in solar photovoltaic cells. Rare earth luminescent glass materials need to have good performance glass materials as the matrix in the preparation process. In the past, most of the matrix glass materials were fluorinated glass, glass-ceramics and glass-ceramics, but the mechanical properties of the matrix glass materials were strong. Silicate glasses with stable chemical properties are relatively rare. In this paper, the preparation of silicate glass doped with rare earth Ce~(3 / Sm ~ (3 +) / EU ~ (3 +) ions was carried out by high temperature melting method, and the luminescent glass samples were obtained. The transmittance curves of glass samples were measured by UV-Vis IR spectrophotometer, the excitation and emission spectra of glass samples were analyzed by fluorescence spectrophotometer, and the glass states of luminescent glass samples were characterized by XRD spectra. A series of properties and spectroscopic tests of rare earth Ce~(3 / Sm ~ 3 / EU ~ (3 +) -doped and double doped glass samples are carried out. The results show that rare earth Ce~(3 / Ce~(3 / Sm ~ (3 / EU ~ (3) -doped silicate glasses can absorb ultraviolet light which is not responsive to semiconductors. And through the downconversion effect, the visible light emitting good luminescence performance.
