ABSTRACT:
A method for producing a fluorescent material involving firing a mixture of a stock material and a flux. The method may involve a first firing process involving firing the mixture of the stock material and the flux in a weakly reducing atmosphere, followed by firing the resulting material in a second reducing atmosphere that is more reducing than the first weakly reducing atmosphere. The flux may include a liquid.
