A green fluorescent body based Zn2SiO4 and process for preparing them

摘要

The present invention relates to a Zn ₂ SiO ₄ -based green phosphor and a method for manufacturing the same, and more particularly, zinc silicate, which is a phosphor matrix, is doped with a manganese oxide as a activator in a predetermined concentration range, so that the luminous efficiency in the vacuum ultraviolet region is improved. The present invention relates to a Zn ₂ SiO ₄ green phosphor for PDP represented by the following Chemical Formula 1 suitable for a plasma display panel (PDP) and a method of manufacturing the same, because it has excellent physical properties even in high vacuum.;In Formula 1, 0 a 0.05.
