Stable ZnSe quantum dots have been prepared by a wet chemical route. Sodium Hexameta Phosphate, an inorganic polymer, is used to encapsulate the ZnSe quantum dots and to enhance the stability of quantum dots. X-ray Photoelectron Spectroscopic analysis confirms the high purity of ZnSe clusters. The optical absorption spectra exhibit a blue shift of about 0.6 eV, suggesting the existence of quantum...
