Fabrication, Deposition, Morphology and Composition of Perovskite CsPb(Br1-xIx)3

Abstract

In this work, CsPb(Br 1-x I x ) 3 perovskite crystals with simple and affordable deposition technique under ambient condition is proposed to be formed. Thus, synthesis of safe inorganic perovskites on glass substrates and bilayer anodic Al/WTi system films was developed by Ligand-Assisted Reprecipitation method immediately on target substrates. Their composition, morphology and photoluminescent characteristics have been studied. Photoluminescence peaks CsPbBr 2 I and CsPbI 3 are 535 and 550 nm respectively and X-ray diffraction analysis show the resulting crystals have an orthorhombic phase. Scanning electron microscopy showed the rod structure of perovskite.
