Display apparatus with coated phosphor, and method of making same
摘要:
Coating phosphor (typically particles) with a thin layer of Si, Ti, Al, Zr, In or Sn-containing material can result in significantly improved lifetime of the phosphor. A preferred coating technique involves exposing the phosphor to an alkoxide (e.g., TEOS) solution having ph>7, preferably >9 or 10.
