Optical, structural and hydrophilic characteristics of synthesized Mn doped SnO 2 thin films

Abstract

Abstract Sol-gel is a good technique and adopted for synthesizing SnO2 and Mn SnO2 nanoparticles then deposited thin films using dip-coater. Absorption was explaining high transmittance for visible region for all samples. XRD patterns where indicate nano crystalline tetragonal phase unchanged when increasing Mn Concentrations. AFM was used to analyze the nature of surfaces and revealed the lowest average roughness (9.489) at (3%), which is a significant finding for self-cleaning technology. Finally, contact angle measurements show that contact angle was change with doping concentration and decrease with increasing UV irradiation time and it changes turbulently and unreliable with increasing irradiation period in the visible region and this indicate good and novel result in Hydrophilicity.
