摘　　要： 采用USB4000光纤光谱仪,在D65参照光源的条件下,测量各个色级不同荧光强度钻石样品的CIE1931色品坐标和主波长,根据色度学原理计算钻石样品的兴奋纯度和亮度纯度。结果表明,对于不同色级而相同荧光强度的钻石,随着色级的降低,钻石的主波长递减,兴奋纯度和亮度纯度递增,即钻石的颜色饱和度增加;对于同一色级的钻石,随着荧光程度的增加,钻石的主波长递增,兴奋纯度和亮度纯度呈减小趋势,强荧光至弱荧光可使钻石的兴奋纯度和亮度纯度上升1到2个色级,即不同程度的钻石荧光可使钻石颜色提升1～2个色级。 In this paper, diamond samples CIE1931 chromaticity coordinates and mian wavelength are measured by using the USB4000 fiber spectrometer under the condition of D65 light source and the samples excitation purity and brightness purity are also calculated according to colorimetric principle. The results show that, for different color grade diamond with the same fluorescence grade, along with the decrease of the color grade, the diamond main wavelength descending, excitation purity and brightness purity increasing, namely the diamond degree of color saturation increasing; For the same color grade diamond, along with the increase of fluorescence intensity, diamond main wavelength increasing, excitation purity and brightness purity showed a trend of de- crease, strong to weak fluorescence can make the diamond excitation purity and bright- ness purity up one to two color grade, that is, different grade of diamond fluorescence can make the diamond color ascension 1~2 color grade.
