Abstract

PURPOSE: The titled cheap fluorescent substance with excellent brightness emitting green light on exposure to UV ray, which has an increased cerium content among rere earth silicate fluoresecent substances activated with cerium and terbium.
CONSTITUTION: A fluorescent substance of the formula[wherein Ln is Y or Gd; x>0; Y>0; 0.7≤(y/x)≤2.5; 3×10-4≤p<6.8×10-1; 3×10-1<q<9.797×10-1; 2×10-2≤r≤3×10-1]. Said fluorescent substance has a strongly excited spectrum at 3650Å in particular and it is possible to make it efficiently luminous by excited spectrum at 3650Å in particular and it is possible to make is efficiently luminous by excitement caused by UV rays of wavelength widely ranging from 2537W3650Å.
