摘要：
The invention relates to phosphor powders and a method for making phosphor powders. The powders are oxygen-containing, such as metal oxides, borates or titanates and have a small particle size, narrow particle size distribution and are substantially spherical. The method of the invention advantageously permits the continuous production of such powders. The invention also relates to improved devices, such as display devices, incorporating those shown by the figure, incorporating the phosphor powders.
