| Abstract: | Superfine MS (M=Cd, Hg, Zn,Pb) with different sizes (average diameter >10nm and average diameter -5nm) are obtained by controlling precipitation. The size of particles are measured via transmission electron microscopy and X-Ray Scattering at small angle. The optical properties of surfine particles are studied at extreme dilution. Smaller crystallites of about 5nm average diameter show large blue shifts in their absorption and ommission spectra. Aging effect in extremely small semiconductor particles are investigated, also. |
