“…Inorganic cesium lead halide perovskite materials CsPbX 3 (X = Cl, Br, I) are widely researched and applied in solar cells, 1,2 LEDs, 3,4 lasers, 5,6 photoelectric detection 7,8 and other fields [9][10][11] due to a direct band gap, high photoluminescence quantum yield (PLQY), great color purity, adjustable wavelength, and ease of synthesis. 12,13 Green and red emission CsPbX 3 materials have been widely studied and rapidly developed with excellent properties.…”
