Amorphous semiconductors are materials with a brilliant prospect for a wide range of optical applications like solar cells, optical sensors, optical devices, and memories. The purpose of the present research was to study the semiconducting optical properties of SiO2-Al2O3-CaF2 and SiO2-Al2O3-BaF2 oxyfluoride...

porous hollow glass microspheres have many uses, including encapsulation of active materials. in this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. then, a highly reactive amine was infiltrated into the etched glass microspheres. scanning electron microscopy was conducted for the hollow glass micr...

bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...
