Photocatalytic activity of zinc stannate: Preparation and modeling

Sonochemical Synthesis, Characterization and Optical Properties of Tb-Doped CdSe Nanoparticles: Synergistic Effect between Photocatalysis and Sonocatalysis

“…Other advantages are the ability to examine the impacts of different variables and their interactions on the output response. Statistical techniques for experimental design can lead to reduced process variability reducing the time, reagents, and experimental work required [ 28 , 29 ].…”

Structural and optical properties of rare earth doped Zn2SnO4 nano-composites prepared via Sol-gel synthesis

“…In UV-Vis spectrometry, regions near IR, VIS and near UV were used to cause electronic transitions in composition under study. In which, at edge of the absorption, the indirect and direct optical transitions occurred [8]. At different wavelengths, required absorption coefficient, near and below each the edge of the curve can be obtained, when I 0 and I represent the intensities of both the incident beam and that transmitted respectively, as follow:…”

“…However, definite reports were explored on possibility of activated Zn2SnO4 by ion for this application. In which, dopants such as the rareearth elements including Tb, Eu, Er, Tm, Ce, Ho, and Nd attracted most of researchers because of the characteristic electronic transitions of them, that could result in sharp luminescence characteristics in range of ultraviolet (UV) to infrared (IR) [8,9]. Zn 2 SnO 4 nanoparticles were synthesized using different methods namely sol-gel synthesis [10,11], thermal evaporation [12], calcination at high temperature [13], coprecipitation method [14,15], mechanochemical synthesis [16], microwave-assisted chemical synthesis [17] and hydrothermal method [18,19].…”
