Structural and optical properties

The aim of the present study is to investigate and compare single thin films with multilayer films consisting of three oxides of zinc, silver, and copper to study the effect of doping on the structural, optical properties, photodetector performances and photocatalysis and the corresponding change of properties depending on the type and percentage of doping

In this work, the effect of annealing temperature and Cr3+ concentration on the structural and optical properties of the SnO2 host crystals has been investigated. The Cr-doped SnO2 samples were synthesized by a simple hydrolysis method, using SnCl4.5H2O as the host precursor and CrCl3.6H2O as the source of dopant.

The 2-methyl-4-nitroaniline (NA) was converted into the raw material N-benzyl-2-methyl-4-nitroaniline (BNA), and the solubility of BNA in various organic solvents was calculated gravimetrically. BNA’s solubility and crystal structure make it an excellent solvent for the low-temperature solution growth method used to create single crystals of BNA with orthorhombic structure studied through single crystal analysis.

In this study, we successfully synthesized europium-doped TiO2 (TiO2 :Eu3+) nanomaterials (NMs) with crystalline sizes ranging from 6.5 to 71.7 nm through a sol-gel method. Analysis of X-ray diffraction (XRD) patterns and ultraviolet-visible (UV-Vis) spectra indicates that the substitution of smaller-sized Ti4+ ions (0.745 Å) by largersized Eu3+ ions (0.947 Å) was more efficient at higher doping concentrations and annealing temperatures.
