A deposited layer of CsI has been prepared at different substrate
temperatures using spray pyrolysis technique. The X Ray diffraction of CsI
films reveals special pattern peaks (110), (200), (211), (220), (310) and (321).
From transmission spectra we calculated the energy gap of CsI films which
increase with increasing deposition temperature for direct transition is
estimated.

In this work, ZnO thin films were grown on sapphire (0001) substrate by
Pulsed Laser Deposition using SHG with Q-switched Nd:YAG pulsed laser operation
at 532nm in O2 gas ambient 5×10-2 mbar at different substrate temperatures varying
from room temperature to 500°C. The influence of the substrate temperature on the
structural and morphological properties of the films were investigated using XRD and
SEM. As result, at substrate 400°C, a good quality and crystalline films were deposited
that exhibits an average grain size (XRD) of 22.42nm with an average grain size
(SEM) of 21.31nm.
