ABSTRACTOptical absorption and photoluminescence techniques were used to investigate the band gap of colloidal CdSe/ZnS core/shell nanocrystals matrixed in a UV curable resin. The band gap was measured for several nanocrystals with size ranging between 1.9 and 4.0 nm. The band gap (Eg) was determined from the first exciton peaks observed in the optical absorption spectra. Both Debye and Einstein temperatures were estimated from fitting the energy band gap vs. temperature using two different empirical expressions.

Comparison Of The Results

Abstract The energy spectra of isomers nos. 11 and 22 of C_84 fullerene is obtained with allowance for the intrasite Coulomb interaction. Based on the obtained spectra, the optical absorption spectra of these systems are simulated. The obtained optical absorption spectra qualitatively agree well with the available experimental data. In addition, the optical absorption spectra are also calculated on the base of the energy spectra of each of the systems calculated without considering the intrasite Coulomb interaction. The comparison of the results obtained in these different models strongly demonstrates the most important role of the Coulomb interaction in the formation of the electronic and optical properties of these systems.

Work Effect

In this work, effect of Li2O and Na2O on bismuth borate glasses have been investigated. The glass samples were prepared in composition 44B2O3 : 50Bi2O3 : 5Li2O : 1A2O3 and 44B2O3 : 50Bi2O3 : 5Na2O3 : 1A2O3 (where A2O3= Sm2O3 and Dy2O3).Glasses were prepared using the melt-quenching technique at 1,100 oc under normal atmosphere. The result found that, the density and molar volume of lithium bismuth borate glasses are less than sodium bismuth borate glasses both in Sm2O3 and Dy2O3. In addition, the optical absorption spectra and luminescence of lithium bismuth borate glasses are higher than sodium bismuth borate glasses both in Sm2O3 and Dy2O3.
