Luminescent materials including Organic and Inorganic Phosphors in powder and thin film forms prepared by various methods and techniques including spin coating, spray pyrolysis, electro-spinning, thermal evaporation, electron beam, etc. With special interest and focus on particle size especially in the nano-scale. Synthesis methods including the conventional solid state technique, the low temperature sol-gel method, the precipitation and co-precipitation methods, the hydrothermal relatively low temperature method, molten flux, etc. Characterization methods including structural, optical, electrical, and thermal analysis, etc.
Investigating experimentally and/or theoretically the structural influence on the optical, thermal, magnetic and electrical properties of various types of materials in different forms including powders, polymers, thin films, and composites in either single or multi layers.
Investigating the effects of various Rare-Earth doping/co-doping on the UV-Vis-IR luminescence behavior of various phosphor materials with the intension of either identifying new potential candidates or improving currently existing ones in terms of their relative intensities, quantum efficiencies, ease of depositions, area coverage, efficient particle sizes, and their concentration quenching curves. Great emphases are focused on the theoretical assignments, explanation and interpretation of the emission/excitation spectra in order to predict and/or consolidate the experimental results and findings.
