为了实现量子点背光源的白平衡,将红量子点和绿量子点与油墨均匀混合,采用丝网印刷的工艺将混合后的量子点浆料印刷到导光板的下表面,作为导光板的网点,在侧边蓝光LED激发下,使红、绿量子点发光并和蓝光共同复合发光。通过调整优化量子点在混合浆料中的比例和红、绿量子点的配比最终实现白平衡。利用OLYMPUS显微镜、F-4600荧光分光光度计和SRC-200M光谱彩色亮度计对量子点网点导光板表面形貌和光学性能进行了表征和分析。实验结果表明:当量子点在混合浆料中的质量分数为7%并且红量子点和绿量子点满足1∶12时,能够实现白平衡,CIE 1931色坐标为(0.330 8,0.327 1),色温为5 588 K,在100 mA的激发电流下亮度可达4.13610

The quantum-dots (QDs) light guide plate (LGP) was prepared with red quantum dots (R-QDs)
green quantum dots (G-QDs) and ink on the surface of PMMA by screen printing. The red and green light emitted from R-QDs and G-QDs which were excited by the side blue LED. The white light was achieved by adjusting the proportion of the QDs in the mixture and optimizing the ratio of R-QDs and G-QDs. The morphology was characterized by OLYMPUS microscope. The LGP optical properties were investigated by F-4600 fluorescence spectrophotometer and SRC-200M spectrum color luminance meter. The results showed that white light could be achieved when the QDs was 7% in the mixture and the ratio of R-QDs/G-QDs was 1:12
which showed the CIE 1931 color coordinates of (0.330 8
