Description
This work studied the structural and luminescent properties of CsVO3 crystals synthetised by the State Solid Reaction doped with Nd3+ ion (0.5, 1, 1.5, 3, 4.5 and 6 mol%). The State Solid Reaction is a versatile and eco-friendly technique potentially applicable in the industry. The X-Ray Diffraction patterns shows that the crystalline structure is the characteristic of the CsVO3, the incorporation of the Nd3+ ion causes the structure to be modified. The excitation spectra of CsVO3:Nd3+ (from 200 nm to 400 nm) show that the band has the maximum at 323 nm, this absorption band corresponding to 1A1 → 1T2 transition associated to [VO4]3-. While the emission spectra from 400 nm to 800 nm, show that the band has the maximum at 535 nm, the band emission in the PL spectra is made up of 3T1 → 1A1 (548 nm) and 3T2 → 1A1 (486 nm) transitions. The Near-Infra Red (NIR) emission of CsVO3:Nd3+ was obtained excited at 808 nm with a pumping power around 370 mW, the maximum in the emission band at 1063 nm corresponding to4F3/2 → 4I11/2 transition of the Nd3+. Near-infrared photoluminescence is useful for applications in optoelectronics and photovoltaics and for such purposes CsVO3:Nd3+ is very promising.
