Influences of Co2+ & Er3+ Co-doping on the Structural and Physical Properties of ZnO Nanocrystals Synthesized by Hydrothermal Route
Co2+ & Er3+ co-doped ZnO nanocrystals were synthesized by the hydrothermal method at 180°C and pH= 12 for 48 h. Powder XRD patterns indicate that the Zn1-2xErxCoxO crystals (0.00<x≤0.035) are isostructural with ZnO. The cell parameters increase for Er3+ and Co2+ upon increasing the dopant content (x). SEM images show that doping of Er3+ and Co2+ into the sites of Zn2+ does not change the morpho...

متن کاملSynthetic Fabrication of Nanoscale MoS2-Based Transition Metal Sulfides
Transition metal sulfides are scientifically and technologically important materials. This review summarizes recent progress on the synthetic fabrication of transition metal sulfides nanocrystals with controlled shape, size, and surface functionality. Special attention is paid to the case of MoS2 nanoparticles, where organic (surfactant, polymer), inorganic (support, promoter, doping) compounds...
متن کاملTransition‐Metal‐Doped NIR‐Emitting Silicon Nanocrystals
Impurity-doping in nanocrystals significantly affects their electronic properties and diversifies their applications. Herein, we report the synthesis of transition metal (Mn, Ni, Co, Cu)-doped oleophilic silicon nanocrystals (SiNCs) through hydrolysis/polymerization of triethoxysilane with acidic aqueous metal salt solutions, followed by thermal disproportionation of the resulting gel into a do...
متن کاملHeavily doped semiconductor nanocrystal quantum dots.
Doping of semiconductors by impurity atoms enabled their widespread technological application in microelectronics and optoelectronics. However, doping has proven elusive for strongly confined colloidal semiconductor nanocrystals because of the synthetic challenge of how to introduce single impurities, as well as a lack of fundamental understanding of this heavily doped limit under strong quantu...
