Synthesis and properties of inorganic organic chloride based perovskite

Abstract

Here we report single step synthesis of lead chloride based organic inorganic hybrid perovskite. Thin films of the material show nanostructured morphology dependent on the fabrication method. Thin films deposited by drop casting method exhibit cubical structures. This morphology changes itself to randomly oriented platelets on spin coating. This evolution of morphology is verified by using scanning electron microscopy (SEM). However as revealed by optical microscopy both the films exhibit identical fluorescence spectra with PL peaks at around 500 nm. Such type of materials may be highly useful in photonic applications requiring varying morphological properties.
