摘要：

Full spectrum/white light-emissive luminescent materials play a key role in boosting the performances of luminescent solar concentrators (LSCs). In this work, a novel type of blue-white light-emitting carbon dots (BWCDs) have first been synthesized by one-step solvothermal strategy based on trisodium citrate and gluta-thione. The BWCDs solution show broad photoluminescence (PL) emission spectrum from 400 to 700 nm and high PL quantum yields (PLQYs) of 13.82 %. A laminated BWCDs based polymer LSC, comprising glass/BWCDs based polymer film/glass, is then created via one-step photopolymerization technique. To simulating the sunlight spectrum, green/red emitting CsPbBr3/CsPbI3 quantum dots (G/RQDs) have further been synthesized and used to coat the bottom and top glass surfaces of laminated BWCDs LSCs, respectively, finally forming multi-emission laminated LSCs. The mutli-emission laminated LSCs (25 x 25 x 2.0 mm3) based on BWCDs and G/RQDs exhibit an external optical efficiency (eta opt) of 3.76 %. Compared to the BWCDs based LSCs,-176 % enhancement in eta opt has been realized. Besides, the multi-emission laminated LSCs exhibit a good transmittance of above 40 % over 520 nm of light wavelength.
