Investigation of the Effect Of Ce3+ Doping on The Luminescent Properties of Baal2o4:Ce3+.

Abstract

Discovery and invention of different luminescent material has greatly contributed to the growth of the global economy, especially the technology. Different elements especially the lanthanides have been research in terms of their properties which plays a great role in the Nano phosphor industry. In this study I considered properties of BaAL2O4. Ce2+ purposely its luminescent properties when codoped with some of the lanthanides elements which include cerium (Ce), .This elements acts as activator ions they tend to increase the afterglow duration when codoped with different phosphor materials. Their effects vary depending on the number and type of ligands directly attached on the metal center of the complex forming the phosphor. In this work I studied the effect of Ce2+ of different masses when doped on the luminescent properties of BaAL2O4. Ce2+ Nano phosphor. In this samples of BaAI2O4.Ce3+ phosphor used in this study will be synthesized using the solution - combustion method. The starting raw materials used in the preparation consisted of analytical pure grade Ba (NO3).4H2O, AI (NO3)3., Ce (NO3)3 and urea (CO (NH2)2) weighed in proportion to the chemical composition of BaAI2O4.Ce3+ and also deionized water, magnetic stirrer and furnace will be included as apparatus for easy of doing the experiment and finding of more accurate results. The mixture will be dissolved in 10 ml of de-ionized water and stirred for 15 minutes at ambient temperature using a magnetic stirrer to obtain a uniform saturated aqueous solution. The solution will be then poured into several crucibles and each placed in a muffle furnace pre-heated to 500⁰C. The final product will be stored in glass bottles while awaiting characterization.
