The transparent and nanoglass-like PbS films were decorated by CBD method on metal substrates at a temperature of 90 °C by aqueous arrays of lead nitrate and thiourea. The XRD level confirms the translucent properties of the combined slim film, and the shape falls into the most commonly oriented cubic design. The ready-made material turned out to be cubic gems arranged as gem layers. The glass-like size varied between 0.4 and 0.7 nm and the tape holes were measured using UV-Vis pinning spectra and tau relations. A typical energy band hole is considered to be 2.43 eV, which is more pronounced than the PbS bulk material. Given the quantum limit of lead sulfide nanoglass-like thin films, PL also confirms this result. Bandhole diversity by sheet concentration and molecular size showed the usual blue behavior for electron quantum confinement. SEM images show very smooth young PbS films seen at high PH values. It was evident that the consistency of mixed thin films decreased from 563 nm to 111 nm with increasing pH. Examples placed at pH 4 show excellent performance, and thin films preserved by removal of avocado leaves (Glycosmis sediments) are a promising strategy to facilitate pollution cleanup and future energy. .
