Preparation and photoluminescence characteristics of In(OH) 3:xTb3+ obtained by Microwave-Assisted Hydrothermal method
(2013-03-15)
Crystalline terbium-doped indium hydroxide structures were prepared by a rapid and efficient Microwave-Assisted Hydrothermal (MAH) method. Nanostructures were obtained at a low temperature. FE-SEM images confirm that these ...

Silanization effect on the photoluminescence characteristics of crystalline and amorphous silicon nanoparticles
(Royal Society of Chemistry, 2013-05)
Silicon nanoparticles synthesized by two different methods, were surface modified with 3-mercaptopropyltrimethoxysilane. The particles of ~ 2 nm size, exhibit photoluminescence (PL) in the UV-Vis range of the spectrum. The ...

Relation between Luminescence and Electronic Surface Characteristics in p-type Porous Silicon
(1997)
Measurements of photoluminescence, electronic surface states and effective surface area, at various stages of the anodization process, are presented. The results show a behavior different from that observed on n-type porous Si.
Europium(III) Concentration Effect on the Spectroscopic and Photoluminescent Properties of BaMoO4:Eu
(Springer/plenum Publishers, 2009-05-01)
BaMoO4:Eu (BEMO) powders were synthesized by the polymeric precursor method (PPM), heat treated at 800 A degrees C for 2 h in a heating rate of 5 A degrees C/min and characterized by powder X-ray diffraction patterns (XRD), ...
