Fabrication of a dye-based random laser using ZnS:Mn quantum dots and investigating the effects of their concentration
Zinc chalcogenide quantum dots (QDs) doped with paramagnetic transition metal ions (particularly ZnS:Mn QDs) are new attractive but rarely examined semiconductor nanocrystals that have excellent welding sweater optical properties and enhanced thermal and environmental stability compared to Cd-based QDs.In this paper, we demonstrate a dye-based rand
