Synthesis and characterization of all inorganic Perovskites

Abstract- Perovskites are ABX3 structures, where A is larger cation, B is smaller cation, and X is 
anion. Recently, metal halide perovskites are studied widely because of outstanding optoelectronic 
applications. Rubidium halide perovskites are rarely reported perovskites. We report on the synthesis 
and characterization of colloidal rubidium lead iodide (RbPbI3) nanowires (NWs). The length of NWs 
is found to be in micron. NWs absorb strongly below 445 nm. Based on morphological and optical 
properties, we predict the possible efficient use of NWs in photodetection devices rather than 
photovoltaic devices because of less absorption in larger portion of visible and infrared spectral range.
Perovskites are used in photovoltaic application, as photo detector, optoelectronic application, color 
conversion LEDs. We synthesized Cesium lead bromide CsPbBr3, cesium lead bromide beta 
cyclodextrin, Molybdenum perovskites and ternary perovskites. We measured their absorbance, 
photoluminescence, photoluminescence excitation and Time Correlated Single Photon counting, to 
measure life time or decay time of photoluminescence.
