采用双高斯函数拟合不同中心波长和带宽的LED芯片光谱，并根据荧光分光光度计的测量结果推算不同LED芯片激发下的Ce/Tb/Eu共掺发光玻璃的发射光谱和色温。结果表明，当芯片带宽不变，中心波长从370 nm右移到378 nm时，Ce/Tb/Eu共掺发光玻璃色温逐渐下降。当芯片中心波长不变，带宽从10 nm增加到25 nm时，Ce/Tb/Eu共掺发光玻璃的色温变化与中心波长有关。在芯片发光稳定的前提下，带宽变化对Ce/Tb/Eu共掺发光玻璃色温的影响小于中心波长改变的影响，故当Ce/Tb/Eu共掺发光玻璃应用于LED发光时，需优先选择芯片的中心波长。

Double Gaussian functions with different center wavelengths or bandwidths were used to fit LED chips spectra. Emission spectra and correlated color temperatures (CCTs) of Ce/Tb/Eu co-doped glasses excited by different LED chips were calculated by experimental results of fluorescence spectrophotometer. When the bandwidths of chips keep unchanged, CCTs of Ce/Tb/Eu co-doped glasses decrease with the red shift of center wavelength from 370 nm to 378 nm. When center wavelength of chips keeps unchanged and bandwidth increases from 10 nm to 25 nm, CCTs of Ce/Tb/Eu co-doped glasses depend on the center wavelengths of LED chips. When the emissions of LED chips are stable, the effect of bandwidth on CCTs of Ce/Tb/Eu co-doped glasses is less than that of center wavelength. So for the application of LED, we should give preference to the center wavelength of LED chips.
