MOISTURE-RESISTANT ELECTROLUMINESCENT PHOSPHOR WITH HIGH INITIAL BRIGHTNESS AND METHOD OF MAKING
摘要
The present invention is an electroluminescent phosphor wherein each individual phosphor particle is encapsulated in an inorganic coating applied by an atomic layer deposition (ALD) coating method. In a preferred embodiment, the coating is aluminum oxyhydroxide. The encapsulated phosphor shows an extreme insensitivity to atmospheric moisture and suffers only minor loss of initial brightness in lamps.
