Document Type and Number:

WIPO Patent Application WO/2006/092990

Kind Code:

A1

Abstract:

A fluorescent substance short in afterglow time and large in luminescence intensity. The fluorescent substance is one that emits light by being excited by the irradiation of an exciting ray, and, when an afterglow curve indicating the relation between an elapsed time (x) after light emission and a luminescence intensity (y) corresponding to that elapsed time is approximated by the following expression (1), its correlation coefficient is at least 0.95. y=Aexp(Bx) (1)
