A method of coating phosphor particles comprises introducing an inert gas into a reaction vessel and charging phosphor particles into the reaction vessel. The reaction vessel is then heated to a reaction temperature and a coating precursor is introduced while the temperature is maintained for a time sufficient to saturate the phosphor particles with the precursor. Thereafter, continuous precursor is introduced into the reaction vessel, along with an oxygen/ozone mixture. The inert gas flow, oxygen/ozone mixture flow and further precursor are supplied for a time sufficient to coat the phosphor particles.
