【摘要】：以艾比湖主要入湖河流博尔塔拉河及精河水体为研究对象,使用寻峰法找出水体荧光峰,采用色坐标分析法对博尔塔拉河与精河水体荧光发射光谱特性及荧光峰的发光性进行分析。首先,博尔塔拉河与精河水体的荧光发射光谱均含有3个荧光峰,各荧光峰的出现位置与峰强度大小均不同。博尔塔拉河第二荧光峰远大于第一荧光峰或第一荧光峰与第二荧光峰基本持平;精河前5个样点的3个荧光峰强度随波长增大呈依次递减分布,6号采样点第一荧光峰与第二荧光峰基本持平。其次,博尔塔拉河与精河3个荧光峰在色坐标中分布位置大致相同,且各点的荧光峰分布较为聚集,均在蓝光区域,属蓝光发射。最后,各荧光峰在CIE坐标中聚集分布,第一荧光峰在色坐标最底端;第二荧光峰分布在第一荧光峰上端,x坐标与第一荧光峰接近;第三荧光峰整体聚集分布在蓝光区域的右上角。
[Abstract]:The main rivers of Ebinur Lake, Boltara River and Jinghe River, were used to find the fluorescence peak of the water body. The fluorescence emission spectra and the luminescence of fluorescence peaks in the waters of Boltara River and Jinghe River were analyzed by color coordinate analysis. Firstly, the fluorescence emission spectra of Boertala River and Jinghe River contain three fluorescence peaks, and the position and intensity of each peak are different. The second fluorescence peak of Boltara River is much larger than the first fluorescence peak or the first fluorescence peak is basically the same as the second fluorescence peak. The intensity of three fluorescence peaks in the first five samples of Jinghe decreased with the increase of wavelength, and the first fluorescence peak of sampling point No. 6 was basically the same as the second fluorescence peak. Secondly, the three fluorescence peaks of the Boltara River and the Jinghe River are approximately the same in the color coordinates, and the fluorescence peaks of each point are concentrated in the blue region, which belongs to the blue emission. Finally, each fluorescence peak is aggregated in CIE coordinates, the first fluorescence peak is located at the bottom of the color coordinate, the second fluorescence peak is located at the top of the first fluorescence peak and the X coordinate is close to the first fluorescence peak. The third fluorescence peak aggregates in the upper right corner of the blue region.
