Synthesis of Co2+ doped Cadmium borate nanopowder for luminescent applications

Abstract

Nanoparticles embedded in host materials exhibit a wide variation in properties, viz., photocatalytic activity, luminescence to name a few. In the present study, Cadmium borate was taken as a host in which addition of Cobalt (Co2+) was done through precipitation method. X ray diffraction (XRD) studies revealed only Cadmium borate peaks (indicating the replacement of Co2+ ions at Cd2+ sites, forming a substitutional solid solution), while morphology was found to be agglomerated irregular particles. Photoluminescent studies indicated their possible application for yellowish green coloured emission.
