| الوصف: | Embedding CsPbX3 (X = Cl, Br, I) perovskites QDs in inorganic glass matrix via in-situ crystallization has been regarded as a feasible strategy to improve their stability against water, heat, and light irradiation. However, the tunable-emission range of these CsPbX3-nanocrystals-embedded glasses is still narrow, insufficient to cover a wide color gamut. Herein, a simple synthetic method was developed in this study to obtain the tunable-emission CsPb(Cl/Br)3 quantum dots (QDs) in boro-germanate glass (CsPb(Cl/Br)3 QDs@glass) by controlling the molar ratio of PbBr2/PbCl2. With the increase of the PbBr2 concentration from 1.6 to 3.2 mol%, the emission wavelength of CsPb(Cl/Br)3 QDs@glasses can be shifted from 448 to 485 nm, and the corresponding photoluminescence quantum yield (PLQY) increases from 0.61 to 24.43%. In addition, the CsPb(Cl/Br)3 QDs@glass exhibits impressing promotion of thermal stability, photostability, and water resistance due to the excellent protective function of the glass matrix. As a proof-of-concept experiment, a LED device was fabricated by employing the optimal CsPb(Cl/Br)3 QDs@glass with a commercial 375 nm UV chip, yielding an intense cyan light. All the results indicate that the investigated CsPb(Cl/Br)3 QDs@glasses may find promising applications as color convertors in wide-color-gamut liquid crystal displays (LCDs). |
