Broad X\u2010ray diffraction peaks suggested the formation of low\u2010dimensional Pr\u2010doped ZnS nanoparticles with a cubic structure that was validated using transmission electron microscopy (TEM)\/high\u2010resolution TEM analysis. The energy gaps were identified using diffuse reflectance spectroscopy and it was found that the values varied between 3.54eV and 3.61eV for different samples. Vibrational experiments on Pr\u2010doped ZnS nanoparticles revealed significant Raman modes at ~270 and ~350\u2009cm<jats:sup>\u22121<\/jats:sup> that were associated with optical phonon modes that are shifted to lower wavenumbers, indicating phonon confinement in the synthesized products. The photoluminescence (PL) spectra of all samples demonstrated that the pure and Pr\u2010doped ZnS nanoparticles were three\u2010level laser active materials. Energy\u2010dispersive X\u2010ray spectroscopy and mapping study confirmed the homogeneous presence of Pr in ZnS. TEM studies showed that the particles were of very small size and in the cubic phase. The samples had high dielectric constant values between 13 and 24 and low loss values, according to the dielectric analysis. With an increase in frequency and a change in the Pr content of ZnS, an intense peak could be seen in the PL spectra at a wavelength of 360\u2009nm, and some other peaks observed corresponded to the transition of Pr<jats:sup>3+<\/jats:sup>. The produced nanoparticles were appropriate for optoelectronic applications due to their short dimension, high energy gap, high dielectric constant, and low loss values.<\/jats:p>","DOI":"10.1002\/bio.4577","type":"journal-article","created":{"date-parts":[[2023,8,10]],"date-time":"2023-08-10T04:01:50Z","timestamp":1691640110000},"page":"1892-1903","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Microwave\u2010assisted synthesis of praseodymium (Pr)\u2010doped ZnS QDs such as nanoparticles for optoelectronic applications"],"prefix":"10.1002","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-3476-7998","authenticated-orcid":false,"given":"Muhammed Jubeer","family":"E","sequence":"first","affiliation":[{"name":"Department of Physics, Farook College University of Calicut  Kozhikode Kerala India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
