Synthesis of lanthanide doped MAl2O4 (M=Ca,Ba,Sr) nano particles and luminescence properties

Phosphorescence, classically, excitation effects (radiation, electron beam, electric field, temperature, etc.) is the name given after the elimination of materials that glow in the visible region. This event continues to glow after the elimination of the effect of excitation is called phosphorescence. In this study were synthesized by the method of the combustion lanthanide doped alkaline earth aluminates. These phosphors after excitation in the visible region to make a long and continuous excitation radiation in terms of the radioactive isotope in terms of not to require great interest. Particles synthesized from the elements with this new kind of phosphorescence as a green / environmentally friendly and energy efficient as functional materials, have a great application potential. High temperature and long reaction time required and the sol-gel method of combustion according to the methods of solid state synthesis temperature lower than the short reaction time, a small particle size, convenience, and is superior in terms of being secured. In this study, the optimal ratio of rare earth elements, in terms of brightness and glow duration was examined by SEM and XRD analysis.
