Optical properties and energy band parameters of luminescent CaMoO 4 :Bi ceramics

Abstract

We studied the role of intrinsic defects of matrix and Bi dopant in the formation of optical properties and energy structure of CaMoO 4 :Bi ceramic. Non-elementary luminescence was detected in a pure CaMoO 4 matrix due to radiative transitions in intrinsic vacancy-type defects, which are associated with non-stoichiometry in calcium. The experiment showed that Bi ions act as quenchers of luminescence. © Published under licence by IOP Publishing Ltd.The work has been funded by the Ministry of (Governmenttask№3.1485.2017/4.6)
