Title:
LIGHT SOURCE WITH NANOMETER-SIZED VUV RADIATION-ABSORBING PHOSPHOR
Document Type and Number:
Japanese Patent JP2005108843
Kind Code:
A
Abstract:
To provide a gas discharge light source having a vacuum ultraviolet ("VUV") radiation-absorbing phosphor.
The light source comprises: (a) a source of plasma discharge that emits electromagnetic ("EM") radiation, a portion of which has wavelengths shorter than about 200 nm; and (b) a phosphor composition that comprises particles, each of the particles comprising at least one type of first phosphor and at least one type of second phosphor. The phosphor composition is disposed such that the first phosphor absorbs substantially the portion of EM radiation having wavelengths shorter than about 200 nm, and the first phosphor emits EM radiation having wavelengths longer than about 200 nm.
