Optical characterization of europium-doped indium hydroxide nanocubes obtained by Microwave-Assisted Hydrothermal method

Abstract

Crystalline europium-doped indium hydroxide (In(OH) 3 :Eu) nanostructures were prepared by rapid and efficient Microwave-Assisted Hydrothermal (MAH) method. Nanostructures were obtained at low temperature. FE-SEM images confirm that these samples are composed of 3D nanostructures. XRD, optical diffuse reflectance and photoluminescence (PL) measurements were used to characterize the products. Emission spectra of europium-doped indium hydroxide (IH:xEu) samples under excitation (350.7 nm) presented broad band emission regarding the indium hydroxide (IH) , but the luminescence is drastically quenched for the IH matrix.

Fast photocatalytic degradation of an organic dye and photoluminescent properties of Zn doped In(OH)3 obtained by the microwave-assisted hydrothermal method

“…The microwave-assisted hydrothermal (MAH) method has unique advantages such as uniform, fast and volumetric heating as compared to other methods and has been efficiently used for the preparation of inorganic materials [31]. Furthermore, this method can significantly reduce the reaction time and the use of high temperatures which promotes rapid crystallization and simplifies the process of preparing nanoparticles [32][33][34][35][36]. Recently, the microwave-assisted hydrothermal method was successfully employed to obtain In(OH) 3 [13,[37][38][39].…”
