Abstract

A wide range of luminescent materials has been produced based on cubic boron nitride and studied by photoluminescence spectroscopy at room temperature and 7 K. These materials were in the form of micropowders, ceramic compacts and polycrystalline aggregates. The luminescence was excited by 325 nm or 488 nm excitation of Eu, Eu-Cr, Er, Sm and Tb additions to the various preparations. Eu-Cr pair emission has been discovered for the first time with its main line at 686 nm in Eu and Cr codoped polycrystalline cBN. The emitted light, which was quite intense in some cases, spanned a wide range of the visible spectrum. It was often highly structured and could be related to the well-known emission characteristics of the 3+ charge states of the relevant ions. The materials have potential applications as phosphors that are required to operate in extreme environmental conditions.
