Enhanced anti-Stokes emission in oxyfluoride glass ceramics for optical refrigeration

The role of fluorine in high quantum yield oxyfluoride glasses and glass-ceramics

“…Herein, we present an optimized composition from the SiO2-Al2O3-YLiF4 system, issued from a previous study [25], and look upon the effect of fluorine concentration on the final glass and glassceramic properties. We investigate the effect of the melting parameters, such as temperature and time factors, on the content of fluorine elements in the final composition.…”
