Abstract
Cu2+ and Sn2+ ions doped MgS nanoparticles were synthesized by chemical route without the aid of any capping agent. The role of Cu2+ and Sn2+ ions on the structural, optical, photoluminescence properties of MgS nanoparticles have been investigated through various analyses like XRD, TEM, EDX UV- vis absorption, transmittance studies, PL spectra and FT-IR. The average particle size was calculated as ∼ 10 nm and it was varied based on the ionic radius of the dopant. From this comparative study, it was observed that Cu2+ (2%) doped MgS showed a blue shift in Absorbance spectra, wide optical band gap and also exhibited better photoluminescence property. A strong PL emission was received in UV region and in the Red region. This combination of materials can be utilized in solar panel manufacturing as buffer material, optoelectronic devices and in red-emitting luminescent displays.
