Manganese doped CdSe nanosheets: Optical and magnetic properties

Cadmium selenide (CdSe) nanomaterial of different shape and sizes has been considered as a suitable material in optoelectronics, lasing devices and sensoric applications. Moreover, the increasing technological demands propose the improvement of their performance. One of theapproach towards controlling the properties is, through doping transition metals. Interestingly, Manganese (Mn) doping introducesspin degrees of freedom into the electronic structure of the CdSeyielding improvedoptical and magnetic properties for accomplishment of next generationopto-spintronics and memory devices. This coexistence of tunablemagnetic and optical properties aspires to this current work where we have synthesized and optimized the Mn doping in ultrathin (thickness 1.5nm) CdSe layered nanosheets (LNS) by a scaffold mediated solvothermal technique. Themagnetic and photoluminescence propertiesexhibitedspin allowed radiative transitionsin comparison with un-doped CdSe LNSs. The schematic of spin-active states rendering selective optical and magnetic properties are shown in Fig. 1.Cadmium selenide (CdSe) nanomaterial of different shape and sizes has been considered as a suitable material in optoelectronics, lasing devices and sensoric applications.
