There is no harmful mercury in WLED. In recent years, the related products have been vigorously promoted to replace the traditional incandescent lamps to achieve the effect of saving energy. Compared to tradition phosphors, luminescent QDs have high PLQY, narrow emission and tunable emissions ranging in the UV to Vis spectral range. As a result, tradition phosphors have been slowly replaced by QDs. The thrust of my master thesis is on the synthesis of zero–dimension PQDs (CsPbX3, X = Cl, Br, I) nanomaterials by microwave-assisted solvothermal method for WLED applications. Most of the PQDs with the best optoelectronic properties are synthesized by toxic lead-containing quantum dots. Hence, my study focuses on divalent cation doped colloidal CsPb1−xMxBr3 PQDs (M = Sn, Mn) featuring partial cation exchange. Finally, WLED is fabricated by using the as-prepared green and red-emitting CsPbX3 QDs as color conversion materials on 450 nm blue LED chip. Chen, Teng-Ming 陳登銘 2018 學位論文 ; thesis 77 zh-TW |
