Magnesium aluminate (MgAl2O4) has received special attention as a technologically important material because of its attractive properties, such as mechanical strength, chemical inertness, a wideband gap, relatively low ...

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 ...

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 ...

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 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 ...

The luminescent properties of yttrium silicate doped with cerium (Y2SiO5:Ce) phosphor thin films were investigated. A detailed investigation (cathodoluminescence (CL), photoluminescence (PL) and Gaussian peak fits) was ...

The optimization of properties for new and potentially useful materials becomes a continuous and sometimes a lifelong process if future applications are anticipated. Research on luminescent materials is a good example of ...

Luminescent lead sulphide (PbS) nanoparticles embedded in an amorphous silica (SiO2) matrix were synthesized at room temperature by a sol-gel process. The prepared nanocomposite materials were crushed into powders and ...
