On the line of a.previous work on the spectra. properties of some of heteroa.yl cha.cone, the effect of medium a.idity a.d photorea.tivity of 3-（4-dimethyla.ino-phenyl）-l-（2,5-dimethyl-thiophen-3-yl）-propenone （DDTP） ha. been investiga.ed in dimethylforma.ide a.d in chlorometha.e solvents such a. methylenechloride, chloroform a.d ca.bon tetra.hloride. The dye solution （ca. 5×10^-4 mol·L^-1 in DMF） gives a.good la.er emission in the ra.ge 470 --560 nm with emission ma.imum a. 515 nm upon pumping by nitrogen la.er （λex=337.1 nm）. The la.er pa.a.eters such a. ga.n coefficient （a., emission cross section （Cre） a.d ha.f life energy （E1/2） a. ma.imum la.er emission a.e a.so determined.
