Sohn, Jiwon; Hwang, Jaehoon; Park, Soo Young; Lee, Geon Joon published the artcile< Carbazole-based photorefractive organic glass showing high diffraction efficiency at low external electric field>, Formula: C19H34O2, the main research area is carbazole photorefractive organic glass diffraction efficiency elec field.
Photorefractive organic glass, 9-(2-ethylhexyl)-3-[2-(4-nitrophenyl)vinyl]-9H-carbazole (EHCN), showing large coupling gain and high diffraction efficiency at low external elec. field was synthesized and characterized. EHCN showed the glass transition at 25° and the good thermal stability up to 400°. Photorefractivity of EHCN was studied by using 100 μm thick films (S1, S2, S3) doped with 0%, 0.5%, and 1% 2,4,7-trinitrofluorenone (TNF), resp. Two-beam coupling net gain of 50.8 cm-1 was obtained for the 0.5% TNF-doped EHCN sample (S2) at 40 V/μm field. The highest internal diffraction efficiency, obtained from the degenerate four-wave mixing at 30 V/μm field, reached 90% for the 1% TNF-doped EHCN sample (S3).
