Solvothermal synthesis and luminescence properties of CdS:Mn nanorods

CdS:Mn nanorods have been produced via a solvothermal approach in the nonaqueous solvent of ethylenediamine. An absolutely dominant single Mn(2+) emission originating from the d-d ((4)T(1)-(6)A(1)) transition was obtained in CdS:Mn nanocrystals at room temperature. The effects of varying reaction temperature, molar ratio of S/Cd, and reaction time on the crystallinity and luminescence of CdS:Mn nanocrystals were systematically investigated. 1% Mn(2+)-doped CdS nanorods without any other additives were synthesized at 130A degrees C for 10 h with an S/Cd molar ratio of 2:1. They show a rod-like shape, and their luminescence intensity around 593 nm is almost the strongest of all the nanorod samples investigated. CdS:Mn nanorods promise potential applications in nanoscale electronic and photonic devices.
