High luminance-phosphor and method for fabricating the same |
摘要 |
A phosphor emits blue color with high luminance and high color purity. The phosphor is fabricated by growing the host material of MX including a II group element (M=Ca, Sr, Zn, Ba or Mg) and a VI group element (X=S or Se) by reacting an M-precursor with a compound including the VI group element, and adding Pb2+ ions into the host material as light-emitting center ions by forming a PbX thin film through a surface saturation reaction between a Pb-precursor and H2X at a reaction temperature higher than a decomposition temperature of the Pb-precursor, wherein the Pb-precursor is a metalorganic compound in which Pb is covalent-bonded with an organic functional group.
