Abstract
A phosphor material contains encapsulated particles of manganese (Mn) doped fluoride phosphor. A method of encapsulating such particles is also provided. Each particle is encapsulated with a layer of a manganese-free fluoride phosphor. The use of such a phosphor material in a lighting apparatus results in improved stability and acceptable lumen maintenance over the course of the apparatus life.
