Thomas, Deepu; Vijayalakshmi, K. A.; Sadasivuni, Kishor Kumar; Thomas, Ajith; Ponnamma, Deepalekshmi; Cabibihan, John-John... more authors ... less authors ( Springer New York LLC , 2017 , Article)Microwave-assisted successive ionic layer adsorption and reaction was employed to synthesize Sn-ZnO (tin-doped zinc oxide), and its sensitivity to ultraviolet radiation is compared with zinc oxide (ZnO). The sensing films ... -
Effect of synthesis conditions on ZnO thin film photosensitivity via mSILAR technique
Thomas, Deepu; Augustine, Simon; Sadasivuni, Kishor Kumar; Cabibihan, John John ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)Zinc oxide (ZnO) nano-polycrystalline thin film has been synthesized by microwave-assisted successive ionic layer adsorption and reaction (mSILAR) technique. The prepared samples were annealed in air and an inert atmosphere. ... -
