Luminescent zinc aluminate (ZnAl2O4) nanoparticles, crystalline–low quartz and amorphous silica powders were incorporated with Ce3+ and Tb3+ ions. These powders were successfully synthesized by the solution combustion and ...

The morphological and luminescent properties of Y3(Al,Ga)5O12:Ce3+ powder phosphor were investigated. Scanning Electron Microscopy (SEM) revealed the phosphor’s agglomerated particles with a size ranging from 0.4μm to ...

Pr3+ ion doped ZnTa2O6, SrTa2O6, CaTa2O6 and ZnTaGaO5 phosphors, which display persistent luminescence were prepared by solid state chemical reaction at 1200 oC for 4 hours. A ZnTa2O6:Pr3+ phosphor that resembled an ...

English: Red glowing phosphors were prepared by adding Pr3+ ions as activators to several oxide host matrixes; CaTiO3, LaTaO4, YTaO4, and GdTaO4. The perovskite CaTiO3:Pr3+ compound is a phosphor that glows with a single ...

This work covers several aspects of rare earth activated silicate and fluoride commercial phosphor powders and thin films. All the films were synthesized by pulsed laser deposition technique using Nd- YAG laser and ...

Phosphate phosphors have emerged as an important family of luminescent material due to their low sintering temperature, broad band gaps, high thermal and chemical stability, and moderate phonon energies. Their structure ...

English: The main aim of this project was to use the technique of pulsed laser depo- sition (PLD) to fabricate thin lms from Yttrium Aluminium Gallium Oxide (Y3(Al; Ga)5O12) doped with Tb3+ ions and then to investigate ...

This work comprises of several aspects of calcium-aluminate phosphor activated with rare earth metal ions i.e. (CaAl2O4:Eu2+, Nd3+, and Dy3+). In particular the luminescent and structural properties of the long afterglow ...

The luminescent and structural properties of the alkaline earth aluminate phosphors prepared by solid state reaction, combustion and sol-gel methods are discussed. The Solid state and Sol-gel methods required much longer ...

Phosphors have many uses today in applications such as electronic information displays, solid state lighting, solar cells, advertising and theft prevention. By using urea-assisted solution combustion method, we prepared ...
