The cesium lead halide (CsPbX3, X = Cl, Br, and I) based perovskite quantum dots (QDs) were synthesized using precipitation and hot-injection methods. And also, the device performance of QD-LEDs using inorganic perovskite (CsPbX3) as emissive layer was characterized. The CsPbX3 showed excellent properties, such as high quantum yield (>~80%), easily tunable band gap, and high color purity as well as high stability. The PL spectra of CsPbX3 were varied by changing the composition of halides. The inverted structure QD-LEDs consisted of ITO/ZnO/poly-electrolyte/PeQDs/MoO3/Ag showed the high color purity EL (Blue : ~480 nm, Green: ~510 nm, Red : ~680 nm) and high brightness (Blue : ~200cd/m2, Green: ~1,200cd/m2, Red : ~300cd/m2).
