title = "Facile room-temperature synthesis of highly air-stable and moisture-resistant CsPbX3/SiO2 nanocomposites for tunable white light-emitting diodes",
abstract = "All inorganic perovskite quantum dots (PQDs) and perovskite CsPbX3/SiO2 nanocomposites (PNCs) have shown their potentials for optical and lighting applications. We demonstrate a one-step approach to synthesize PQDs and PNCs more simply and effectively at room temperature in the open air. The resulting PNCs can show a narrow emission in the PL spectra and high stability under ambient conditions. In particular, both green CsPbBr3/SiO2 and red CsPbI3-xBrx/SiO2 PNCs can be obtained by employing this easy and low-cost method. Even, the SiO2 protection can also effectively prevent the halide exchange reaction between green and red PNCs, meaning the capability for white light applications. The resulting white light-emitting diodes (WLEDs) based on the green and red PNCs coated on the blue LED have a white Commission Internationale del{\textquoteright} Enclairage (CIE) coordinates of (0.375, 0.362) and a low correlated color temperature (CCT) of 4054 K.",

note = "Funding Information: Fig. 7(a) and (b) show the PL intensities as a function of time after injecting to DI water, The PQDs without SiO2 wrap show serious degradation and lose the fluorescence in ~10 s, as seen in the video file in the supporting information. In contrast, The PNCs reveal high resistance to the water and maintain the fluorescence over 6 h, which is similar to previous reports [26, 36–38].This work was supported by the Ministry of Science and Technology, Taiwan, under Grant No. MOST 108-2221-E-131-009-MY2.
