Using a microwave-assisted hydrothermal method, we synthesized BiOBr powders, with and without, glycine or phenylalanine as templates. The samples were characterized by X-ray Diffraction, UV–Vis Diffuse Reflectance Spectroscopy, and Field Emission

In this work, we investigate the synthesis of LiGa5O8 ceramic powders through a polyvinyl alcohol-based sol-gel technique and their optical properties when doped with high Cr3+ concentrations (5, 25 and 50 mol% with respect to the Ga3+ sites). The re

Bi2-xCaxSn2O7-x/2 ceramics were synthesized by solid-state reactions and sintered at 1050 °C. Raman and infrared spectroscopies were used to investigate the optical vibrational properties of pure Bi2Sn2O7 ceramics, as well as to understand the influ

SrAl 2 O 4 is one of the most investigated phosphors for long lasting phosphorescence, mainly when activated with Eu 2+ ions. Usually Eu 2+ is obtained by the Eu 3+ reduction during the material synthesis under a reducing atmosphere, such as H 2 for

Barium-doped La 2 NiMnO 6 double perovskites have been investigated in order to elucidate the role of the B-site doping on its magnetic, dielectric and vibrational properties. In all cases, we have obtained a non-linear dependence with the Barium con

We have investigated the temperature-dependent Raman-active phonons and the magnetic properties of Gd(Co1/2Mn1/2)O3 perovskite ceramics in the temperature range from 40 K to 300 K. The samples crystallized in an orthorhombic distorted simple perovski
