Luminescence Characterization of ? - Irradiated Ce Doped Barium Orthovanadate Phosphors

Vikas Gulhare, R. S. Kher, S. J. Dhoble


Abstract: Present paper reports mechanoluminescence (ML), thermoluminescence (TL) and photoluminescence (PL) in ? - irradiated Ce doped barium orthovanadate pohsphors. Barium orhtovanadate and barium metavanadate having different concentration of Ce were prepared by solid state diffusion technique. The ML intensity increases with increasing concentration of dopant and it is found maximum for the sample having 0.1 mol% concentration of Ce. The dependence of ML intensity on ? - dose has also been studied. In TL glow curve of Barium orhtovanadate sample one single peak appears around 1200C. ML and TL spectra contain a sharp peak around 480nm. In the PL of barium orthovanadate a sharp peak at 364nm is obtained along with a broad band around 470 nm. Barium metavanadate shows very weak ML and TL as compared with barium orthovanadate because of less probability of formation of trapped hole centers. The similarity of ML and TL emission suggests that the excitation process is governed by the states of the similar nature.
