GREEN LUMINESCENT FLUORESCENT CONTAINING BORIC ACID-ALUMINUM AND FLUORESCENT LAMP USE THEREOF

摘要

A boric aluminum system green-emitting fluorescent material has a composition formula of 2Al2O3 B2O3:Tbx, My (wherein M is at one element selected from goup of Ce, Sc, Lu, La, In and Y; 0<=x<=0.5 ; 0<=y<=0.5). Pref. the amount of terbium (x) and M (y) are 0.001<=x<=0.09 and 0.01<=y<=0.3 respectively. And the fluorescent lamp is prepared by forming the fluorescent screen, which includes green-emitting fluorescent material, on the inner surface of the tube.
