Experimental results align with theoretical predictions.

Abstract

The manuscript reports experimental estimation of Cesium Chloride film's band gap and compares it with theoretical simulations. The band gap shows a strong dependence on it's lattice constant. Also, it is seen that the point defects present in the films strongly affects it's optical properties.
