Organic light-emitting field-effect transistors (OLEFETs) are regarded as a novel kind of device architecture for fulfilling electrical-pumped organic lasers. However, the realization of OLEFETs with high external quantum efficiency (EQE) and high brightness simultaneously is still a tough task. Moreover, the design of the resonator structure in LED is far from satisfactory. Here, OLEFETs with EQE of 1.5% at the brightness of 2600 cdm−2, and the corresponding ON/OFF ratio and current efficiency reaches above 104 and 3.1 cdA−1, respectively, were achieved by introducing 1,4,5,8,9,12-hexaazatriphenylene-hexacarbonitrile (HAT-CN) as a charge generation layer. Moreover, a vertical microcavity based on distributed Bragg reflector (DBR) and Ag source/drain electrodes is successfully introduced into the high performance OLEFETs, which results in electroluminescent spectrum linewidth narrowing from 96 nm to 6.9 nm. The results manifest the superiority of the vertical microcavity as an optical resonator in OLEFETs, which sheds some light on achieving the electrically pumped organic lasers.

“…The dielectric layer was made up of 350 nm poly-4-vinylpenol (PVP) and 30 nm polystyrene (PS), which was prepared by spin-coating in a method reported elsewhere. 28 Pentacene (15 nm), MoO x (0.25 nm), CBP:Ir(piq) 2 acac (weight concentration of approximately 6%) (20 nm), and TPBI (14 nm) were successively thermalevaporated at rates of 0.2, 0.05, 2, and 0.2 Å/s, respectively. The asymmetric source and drain electrodes were evaporated at a deposition rate of 0.3 Å/s by rotating the substrates at a fixed angle to control the channel length to be 120 μm and a channel width 3 mm through a shadow mask, followed by the deposition of PTCDI-C13 (P13, 30 nm) at a rate of 0.5 Å/s.…”

Improved performance of multilayer heterostructure organic light-emitting transistors (OLETs) was observed in brightness and external quantum efficiency (EQE) by inserting an ultrathin MoO x layer and TPBI buffer layer. With in-plane emission mainly beneath the drain electrode with a maximum width of 120 μm, an EQE of 0.16% at a brightness of 238 cd/m2 was obtained. Different sizes of pixeled OLETs were fabricated by restricting the pixel length by narrowing the width of the gate electrode perpendicular to the source/drain electrodes. Light emission pixels with sizes from 25 to 400 μm have been successfully demonstrated. The maximum width of the emission zone was not affected, and the maximum EQE and the corresponding brightness presented an increasing tendency for pixeled OLETs. The results in our work are helpful for developing a new generation of OLET-based display technology.

A stable n-type semiconductor material, ZnPcF 16 , was synthesized and characterized by infrared (IR), UV-vis and uorescence spectra. ZnPcF 16 showed a monomer characteristic in 1, 2-dichlorobenzene (DCB) while exhibited an aggregation property in tetrahydrofuran (THF) and dimethylformamide (DMF). The ZnPcF 16 /p-6p (ZnPcF 16 on p-6p) organic thin lm transistors (OTFTs) using ZnPcF 16 as an active layer and p-6p as an inducing layer was fabricated by the physical vapor deposition technique. The ZnPcF 16 semiconductor lm was characterized by XRD and SEM. And the results showed that ZnPcF 16 molecules can be oriented after the employment of the p-6p inducing layer. Charge carrier eld-effect mobility (µ) and threshold voltage (V T ) of the ZnPcF 16 /p-6p OTFTs were 1.3 × 10 −2 cm 2 /V s and 22 V, respectively.
