  author={R. Reisfeld and Y. Kalisky},
The use of uranyl doped glasses for solar energy conversion and concentration was discussed by Reisfeld and Neuman1. While the UO2+2 ion is an efficient energy converter, its maximum emission peaking around 500 nm does not coincide with the maximum sensitivity of the existing solar cells which is around 700–1,000 nm. The use of Nd3+ doped glasses for solar energy collectors was described by Levitt and Weber2. While the emission of Nd3+ peaking at 880 nm (4F3/2→4I9/2) and at 1.06 µm (4F3/2→4I11… Expand
