Abstract

A novel efficient (Φ=0.44) organic yellow-emitting dye, 3-(4-(diphenylamino)phenyl)-1-phenylprop-2-en-1-one (DPPO), was synthesized. The compound was characterized by means of 1H NMR and differential scanning calorimetry (DSC) and analyzed by quantum chemistry method. It was found that DPPO could be effectively excited by the InGaN-based blue LED. Photo-durability data of DPPO were studied. Bright white light of Commission International del' Eclairage (CIE) x=0.30, y=0.33 was obtained by using DPPO as a light color-conversion material (CCM). © 2007 Elsevier B.V. All rights reserved.
