Luminescence of Cesium Thiocyanate (CsSCN) doped with Eu2+ (CsSCN:Eu2+)

Abstract

Many host lattices have been investigated, as it is known that the effect of the host lattice in luminescence is complex, therefore this work seek to investigate Cesium Thiocyanate (CsSCN) as a suitable host lattice in luminescence. Cesium Thiocyanate is doped with EU 2+ and the Luminescence of the doped compound measured. CsSCN was prepared from Cd(SCN) 2 and Ca(CO) 3. The prepared CsSCN was then doped with 0.05% EU 2+ at 220 oc. The Luminescence spectra of the CsSCN:EU 2+ was measured using a D5000diffractometer. The emission spectra obtained is broad with the maximum at 19801cm-1. The spectra obtained were in agreement with typical thiocynante spectra that were doped with EU 2+. CsSCN can therefore be used as a host lattice with some minor problems of decomposition by products.
