In this study we used CH<inf>3</inf>NH<inf>3</inf>SnCl<inf>3</inf> perovskite wherein CH<inf>3</inf>NH<inf>3</inf>Cl and SnCl<inf>2</inf> solutions are the precursors. These two precursors are mixed with ratios of 3:1, 1:1 and 1:3. XRD, UV–Vis absorption and photoluminescence studies were carried out in both solution and film form. © 2020 Elsevier B.V.Chlorine compoundsMixingPerovskitePhotoluminescenceTin compoundsAbsorbancesMixing ratiosPhotoluminescence intensitiesTin chloridesVis absorptionNitrogen compounds
