The recent resurgence of photovoltaic research has empowered all inorganic perovskite materials to take the center stage thus leading to a plethora of interesting results. Here, via a facile room-temperature synthesis protocol high quality cesium lead halide perovskite (CsPbBr2Cl) cubes has been realized. Surface morphology and crystallinity of the synthesized sample were investigated by FESEM and XRD respectively. To attain detail information of its chemical composition EDX analysis and elemental mapping were carried out. These single crystalline cubes crystallize in orthorhombic phase and exhibit strong photoluminescence emission at 482 nm with narrow FWHM value (∼18nm) and photoluminescence decay time of 10.44 ns. We believe, this facile synthesis protocol will pave the way for realization other perovskite cube and thereby their usage in several optoelectronic arena like as lasing, LEDs and photo detector etc.
