Abstract:
Highly luminescent CdSe nanocrystals have been assembled on glass/ ITO substrates using a wet synthesis route. The physical properties of the quantum dots have been investigated using optical absorption spectroscopy techniques. The optical transition energies have been determined for the lowest electron- hole pair states of CdSe quantum dots embedded in glass. The differential absorption spectra have been compared and general size dependence could be established. Considering theoretical models, the dominant features have been assigned to different transitions from the ground state to the one pair state.
