✦ Synopsis

The features of fluorescent glass solar collectors are discussed Combination of Nd3+ and Yb3+ in hi$r refractive index glasses is suggested as concentration material. Enemy absorbed by Nd at 970 nm. The self-absorption of Nd3* _ 3 + is transferred with high efficiency to Yb3 + emitting IS eliminated and long-wavelength emission at 1.06 pm decreased as a result of energy transfer. * Supported by the Israel Ministry of Energy. ** "Enrique Berman" Professor of Solar Energy.
