Structural optical and electrical properties of vanadium
However very little literature is available on the V-doping of BCZT ceramics so it becomes an interesting material to study in detail. Furthermore V is a narrow-bandgap material and doping it into BCZT which is a wideband material can facilitate high visible-light activity and improve the optical properties of BCZT ceramics.

Optical and Electrical Properties of ZnSe Cu Ceramics
Mar 01 2001 · ZnSe Cu ceramics were prepared by hot-pressing powder mixtures of ZnSe and Cu at 900–1200°C under a pressure of 30 MPa. The luminescence spectra of the ceramics were found to be dominated by a green emission centered at 540 nm whose intensity can be controlled by varying the Cu concentration and hot-pressing temperature. The nature of the green-emission centers is discussed.
