Abstract
The quantized energy states of CdS quantum dots as probed by optical absorption and photoluminescence (PL) spectroscopy are reported. The PL spectra show a strong emission band corresponding to electron-hole recombination and weak band due to emission from defect states and the strength of electron-phonon couple is small in the regime of strong confinement and decreases with decreasing particle size.
