Abstract

Se describen partículas de fósforo de tioaluminato que tienen un revestimiento que comprende o que consiste esencialmente en un nitruro, y métodos para preparar tales partículas de fósforo; los diodos emisores de luz convertidos en fósforo pueden comprender tales partículas de fósforo revestidas; los revestimientos de nitruro sobre las partículas de fósforo de tioaluminato proporcionan una barrera al agua significativamente mejorada en comparación con un revestimiento de óxido de aluminio y extienden la vida operativa de dicho diodo emisor de luz convertido en fósforo.
