Synthesis and Characterization of Zn1-X Crxo Thin Films Deposited by Chemical Spray Pyrolysis Technique

Abstract

In this study, chemical spray pyrolysis system were using to prepared the Zn1-xCrxO films where x (0, 1, 3, 5 and 7) %. Structural and optical properties is studies by XRD and UV\VIS\NIR spectroscopy. Were the average crystial size estimated by Scherers method and the Dave value decreases as CrO increasing and the value about (35.6- 10.7) nm. The energy gap for thin films increases as the CrO increasing starting (0 to 7) % to reach it is maximum value of (3.38eV). The transmittance value of undoped ZnO equal 90% and the The transmittance value decresing when ratio of doped by CrO inecresed.
