Structural and optical studies on La doped CdS nanocrystalline films

Morphological, Photoluminescence, and Electrical Measurements of Rare-Earth Metal-Doped Cadmium Sulfide Thin Films

“…The doping mechanism is the most popular method for modifying semiconductors’ structural, morphological, optical, and electrical characteristics. Sm and La have been shown to have an essential role in altering the critical optoelectrical characteristics of numerous semiconductor materials, including CdO, TiO 2 , ZnS, and ZnO. − The significant difference in radius and charge between rare-earth trivalent ions (RE 3+ ) and divalent cadmium ions (Cd 2+ ) often impedes the successful integration of RE 3+ into CdS, resulting in suboptimal energy transfers. Although the characteristics of many nanoparticles infused with lanthanide ions have been documented, yet a majority of them should be synthesized using high-temperature methods. , This synthesis typically results in particles devoid of organic groups on their surfaces.…”
