Synthesis and observation of a correlation between the Raman spectra and photoluminescence (PL) of silicon nanoparticles (Si-nps) embedded in Al2O3 matrix grown by reactive pulsed laser deposition in oxygen atmosphere are reported. We observed a strong dependence of the band gap, photoluminescence ...

of Al content on Raman spectra of aluminosili-cate minerals were investigated. The result shows that there is a decreasing tendency in frequencies ranging from 800—1200 cm–1 with the increasing of four-coordinated Al content, and Raman scattering bands in the range were assigned to Si—O nb...
