In this letter, a novel hole transport layer (HTL) of poly-(Nvinylcarbazole) (PVK) doped with poly[bis(4-phenyl) (2,4,6-trimethylphenyl)amine] (PTAA) was employed in solution processed CH3NH3PbBr quantum dots light-emitting diode (QLED). By optimizing the doping ratio of the PVK and the PTAA, the hole transport ability could be effectively improved, and the hole injection barrier could also be red...Show More
In this letter, we synthesize and characterize a new series of organic/inorganic hybrid quasi-2D perovskites PEA 2(FA)n–1PbnI3n+1 ( $n = 2, 3, 5$ ). The quantum well thickness of perovskites could be adjusted by regulating the crystal structure, which resulted in a tunable bandgap and emission spectra. The deep-red emissions from the flexible light-emitting diodes have been successfully achieved. ...Show More
Organic light-emitting diodes with low driving voltage based on fullerene $({\rm C}_{60})$ as an electron transport layer and tris (8-hydroxyquinolinato)-aluminum $({\rm Alq}_{3})$ as a buffer layer are successfully fabricated. For the optimal device with structures of ITO/NPB (40 nm)/${\rm Alq}_{3}$ /(30 nm)/${\rm C}_{60}$ (20 nm)/${\rm Alq}_{3}$ (3 nm)/LiF (0.8 nm)/Al (120 nm), the turn-on driv...Show More
The performances of blue organic light-emitting device based on N-BDAVBi are enhanced by inserting a CuPc electron buffer layer, which improves the injection of electrons. By adjusting the thicknesses of the CuPc electron buffer layer and the MoO3 hole buffer layer, the maximum luminescence, the current efficiency, and the power efficiency of above devices have been approximately enhanced by 113%,...Show More
A crystalline organic field effect transistor (OFET) with the polarizable material of 2-(4-hydroxyphenyl)-5- pyrimidinol was accomplished in thermal vacuum evaporation system. In the measurement for the devices, three types of IDS -VDS curve with the applied VG were found, in which the anomalous electrical properties from the devices were obtained, including the normal IDS-VDS curves of OFETs, the...Show More
A liquid organic field effect transistor (LOFET) which active material was a polarizable chemical (2-(4-hydroxyphenyl)-5-pyrimidinal) was fabricated. The current through source electrode and drain electrode presented the vibration with the measured time under the different Gate voltage. The dependence of the periodical vibration time on Gate voltage was obtained. We supposed a polarized model to e...Show More
