de Oliveira, R. C. [UNESP]; Silva, A. C.A.; Dantas, N. O.; Guerra, J. D.S.Made available in DSpace on 2019-10-06T15:35:22Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-09-10; Tellurite-based (TeO2) glass systems are known to have relatively high chemical and thermal stability, high transmittance in the infrared region as well as low light dispersion. Parallel to the investigations of the optical properties of the TeO2-based glasses, there is a growing interest in the manufac...

Freitas Neto, E. S.; Silva, S. W. da; Morais, P. C.; Vasilevskiy, Mikhail; Silva, M. A. Pereira da; Dantas, N. O.Optical phonon modes, confined in CdSxSe1−x nanocrystal (NC) quantum dots (≈2 nm in radius) grown in a glass matrix by the melting-nucleation method, were studied by resonant Raman scattering (RRS) spectroscopy and theoretical modeling. The formation of nanocrystalline quantum dots (QDs) is evidenced by the observation of absorption peaks and theoretically expected resonance bands in the RRS excitation spectra....
