This review summarizes the recent progress of efficient room temperature phosphorescence (RTP) from pure organic luminogens achieved by crystallization-induced phosphorescence (CIP), with focus on the advances in our group. Besides homocrystals, mixed crystals and cocrystals are also discussed. Meanwhile, intriguing RTP emission from the luminogens without conventional chromophores is demonstrated.
The spectra of Eu3+-doped Y2SiO5 crystal were detected. The Judd-Ofelt intensity parameters Omega2 , Omega4 and Omega6 were calculated according to the absorption spectra, and were equal to 4.36 times 10 -20 cm2, 0.74 times 10-20 cm2 and 1.074 times 10-20 cm 2, respectively. Persistent spectral hole burning (PSHB) were also observed at the temperature of 4.2K in the crystal. For 15mW dye laser (wavelength:...
