Fotokonduktor organik (OPC) telah menjadi topik penyelidikan dan pembangunan yang penting untuk elektrofotografi berkualiti tinggi. Dengan menggunakan pengukuran penjanaan harmonik kedua optik (EFISHG) teraruh medan elektrik, kita boleh menyiasat proses pembawa dalam proses elektrofotografi seperti penjanaan pembawa foto, pemisahan pembawa dan pengangkutan pembawa untuk penghasilan imej mesin fotokopi. Kami di sini secara selektif menyiasat penjanaan dan pengumpulan cas dalam lapisan penjanaan cas dan lapisan pengangkutan cas dalam OPC struktur berbilang lapisan. Kami mengkaji pengumpulan cas dalam OPC di bawah pencahayaan (panjang gelombang 635nm) OPC jenis dua lapisan dengan struktur lapisan pengangkutan lubang bersalut pada lapisan penjanaan cas. Keputusan menunjukkan bahawa penyerapan cahaya dengan cekap menghasilkan lubang dan elektron bebas dalam lapisan penjanaan cas, diikuti oleh pengumpulan lubang yang berlebihan pada antara muka CG/CT disebabkan oleh kesan pengalir foto lapisan CG. Penyinaran panjang gelombang pendek pada kesan fotovoltaik teraruh 405nm. Keputusan ini menunjukkan bahawa pengukuran EFISHG berguna untuk menyiasat proses pembawa secara selektif dalam satu lapisan OPC berbilang lapisan dan untuk perbincangan proses pembawa untuk penghasilan imej elektrofotografik.

Abstract: Organic photoconductors (OPC) have been an important research and development topics for high quality electrophotography. By using electric field induced optical second harmonic generation (EFISHG) measurement, we can probe carrier processes in electrophotographic processes such as photo carrier generation, carrier separation, and carrier transportation for copier image production. We here selectively probe charge generation and accumulation in charge generation layer and charge transport layer in multilayer structure OPCs. We studied charge accumulation in OPC under illumination (wavelength 635nm) of double-layer-type OPC with structure of hole transport layer coated on charge generation layer. The result showed that light absorption efficiently produces free holes and electrons in the charge generation layer, followed by excessive hole accumulation at the CG/CT interface due to photo-conducting effect of CG layer. The short-wavelength irradiation at 405nm induced photovoltaic effect. These results demonstrated that the EFISHG measurement is useful to selectively probe carrier process in one layer of the multilayer OPC and to the discussion of carrier process for electrophotographic image productions.
