Abstract

Manganese-doped cadmium selenium quantum dots (Mn-doped CdSe QDs) were successfully synthesized in the absence of trioctylphosphine (TOP) at various ripening temperatures and times. The TEM image shows the QDs with average particles size of 5.3nm with almost spherical shape. The optical properties of Mn-doped CdSe QDs were investigated using ultraviolet-visible and photoluminescence spectroscopy. The behavior of Mn-doped CdSe QDs was monitored using the red-shift characteristics in the UV-Vis absorption spectra, and their size variations were estimated by the quantum confinement theory. The PL emission spectra of Mn-doped CdSe QDs shows similar evolution behavior as in the absorption behavior. Quantum confinement allows tuning of the CdSe bandgap energy across the Mn excited-state energies. The origin of stokes shift were discovered.
