Effect of NaCl on the luminescent behavior of CsI thin films.

ABSTRACT: In recent years, several reports have shed light on the growing interest in modulating the optoelectronic properties of cesium iodide (CsI) thin films for enabling their application in low-cost and eco-friendly luminescent devices. However, traditional techniques used for such modification like annealing, doping, and nano-structuring, often demand high temperatures or vacuum processing, limiting their large-scale scalability. Herein, we report a simple, eco-friendly method to tailor the luminescent properties of CsI thin films by incorporating NaCl via a simple aqueous based, low-temperature (∼50 °C) process. CsI/NaCl films prepared in a 1 : 1 molar ratio of CsI and NaCl, exhibited strong UV-excited photoluminescence at ∼415 nm, with significantly longer radiative decay times (τ<
