Abstract

The effect of Chemical bath deposition conditions (deposition temperature and deposition period) and potassium hydroxide KOH concentration on the optical and structural properties of CaO thin films have been investigated. The films subjected to different techniques including field emission scanning electron microscope FESEM, UV-visible spectrophotometer and X-ray spectroscopy to explore their properties. The FESEM images and X-ray spectrums of the films show a clear effect of the KOH concentration, deposition temperature and period on the grain size and films properties, where the grain size varied with deposition temperature from 43nm to 102nm, while it changed with KOH concentration from 43nm to 115nm and with deposition period varied from 36nm to 74nm.
