Luminescence in semimagnetic Pb1−xMnxSe quantum dots grown in a glass host: Radiative and nonradiative emission processes

► Pb1−xMnxSe QDs were synthesized in a glass matrix by fusion method. ► The sp-d exchange interaction taking place in QDs DMS provides a unique interplay between optical properties and magnetism. ► PL spectra showed the luminescence transition in Pb0.95Mn0.05Se QDs. ► Electron Paramagnetic Resonance spectra confirmed that Mn2+ ions are located in two distinct PbSe QDs sites.
