摘　　要：报道了一种新的可用蓝光发光二极管(LED)有效激发的黄色发光玻璃.这种超宽带黄色荧光玻璃样品是在低硅钙铝酸盐玻璃基质中掺杂Ce^(3+),并采用熔融法制备的.通过对吸收光谱、激发光谱、荧光光谱以及不同激发源下荧光强度和峰值波长的测试,分析了样品的发光特性.并利用蓝光LED来激发样品,获得白光发射.从色坐标的计算和玻璃本身的优势来看,这一发光体系在照明和显示等方面具有很大的潜在应用价值.We present a new glass able to produce ultra-broadband yellow fluorescence. The luminescence system is Ce3＋ doped low silica calcium aluminosilica glass excited by blue light emitting diode （LED）. The glass is prepared by the conventional melting process. We analyze the luminescence properties of the samples by measuring their absorption spectra, excitation spectra, fluorescence spectra. Furthermore, we study the influence of excitation wavelength on the fluorescence intensity and peak wavelength. The doped glass combined with blue LED to obtain the white lighting is achieved. Besides we calculate the Commission Internationale de I＇Eclairage chromaticity coordinate. Therefore these glasses have large potentials to be used as white lighting phosphor materials.
