A blue luminescent silica monolithic aerogel was prepared by a sol-gel process followed supercritical drying. The as-prepared silica aerogels are transparent and exhibit blue luminescence excited by a near UV light of 365 nm wavelength. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that the monolithic aerogel had micropores and nanopores. Small angle X-ray...
CdS, ZnS, and Zn x Cd 1-x S alloy were deposited from acidic solutions by the electrochemical technique, and characterized mainly by optical methods. Raman scattering was observed even for as-deposited films, and the alloy composition x was determined from the longitudinal-optical phonon frequency. Photoluminescence (PL) was detected at 77 K after annealing at 300°C. The...
