Abstract
PURPOSE: The titled substance, which has a high emission efficiency, is stable thermally, chemically and physically, and comprises a crystalline organic carboxylic acid salt containing a rare earth element consisting of an organic carboxylic acid radical having a carboxylic acid group linked to a specific organic group and a rare earth element.
CONSTITUTION: A substance comprising a crystalline organic carboxylic acid salt containing a rare earth element which consists of (A) an organic carboxylic acid radical wherein (i) a carboxylic acid group is linked to (ii) an organic group having three or more conjugated groups capable of being conjugated with (i), e.g. a π conjugated group such as -C=C-, preferably a(n) (un)saturated aliphatic, aromatic hydrocarbon group, quinone residue or a heterocyclic group containing an oxygen etc. sd a hetero atom, and (B) a rare earth elements, e.g. praseodymium or europium. One or more types of the titled substances as an illuminating component provide a mass-producible illuminant of high emission efficiency readily.
USE: A basic material for optoelectronics, e.g. laser.
