Abstract

We experimentally demonstrate high-speed visible light communication (VLC) and high-quality solid-state lighting (SSL) using polymethyl-methacrylate-doped phosphor film based on cesium lead bromide quantum dot (CsPbBr-QD) and potassium fluorosilicate KSiF:Mn, which is excited by a blue gallium nitride laser diode. A 1.6 Gbps data rate is achieved by employing a non-return-to-zero on-off keying modulation scheme. The measured bit error rate of 2.7×10 adheres to the standard threshold (3.8×10) of forward error correction. Moreover, the generated white-light source has a high color rendering index of 93.8 and a correlated color temperature of 4435 K, and it exhibits a Commission Internationale de l'Eclairage (CIE) 1931 chromaticity coordinate at (0.3556, 0.3520), which is close to the ideal CIE value of white light (0.3333, 0.3333). This work opens up exciting possibilities for future high-speed indoor VLC and high-quality SSL.

摘要

我们通过实验证明了基于溴化铯铅量子点（CsPbBr-QD）和氟硅酸钾KSiF:Mn的聚甲基丙烯酸甲酯掺杂磷光体薄膜实现了高速可见光通信（VLC）和高质量固态照明（SSL），该薄膜由蓝色氮化镓激光二极管激发。通过采用非归零开关键控调制方案实现了1.6 Gbps的数据速率。测得的误码率为2.7×10，符合前向纠错的标准阈值（3.8×10）。此外，生成的白光源具有93.8的高显色指数和4435 K的相关色温，其在国际照明委员会（CIE）1931色度坐标为（0.3556, 0.3520），接近白光的理想CIE值（0.3333, 0.3333）。这项工作为未来的高速室内VLC和高质量SSL开辟了令人兴奋的可能性。
