Xiang Li, Peng Yuan, Jinyu Song, Yu Chang, Xueting Jiao, Jianfen Zhao, Cong Zhang, Wenjuan Li, Xiao-Chun Hang

Summary: In organic light-emitting diodes, the migration rate of positive and negative charge carriers differs, leading to the migration of excitons to the hole transport layer and the electron transport layer. This study focuses on designing high-quality multi-resonance hosts to balance the migration rate. Two newly developed multi-resonance hosts, m-ICzPBI and o-ICzPBI, containing an indolo[3,2,1-jk]carbazole (ICz) motif, were reported. The devices constructed with these hosts achieved high efficiency and low efficiency roll-off.

Highly thermal stable and efficient carbazole/pyridine/dibenzothiophene based bipolar host material for red phosphorescent light-emitting diodes

Liang Zhao, Xiaozhe Cheng, Weizhen Xia, Lingling Yao, Zhitao Dou, Haibin Xue, Hong Lian, Yongquan Qu, Qingchen Dong

Summary: In this study, two bipolar host materials, DBTPC1 and DBTPC2, were designed and synthesized using different linkages between carbazole, pyridine, and dibenzothiophene. The photophysical and thermal properties of these hosts were systematically investigated. The rigid molecular structures of these hosts contribute to high glass transition temperatures, ensuring excellent thermal stability. When used as hosts in red phosphorescent organic light-emitting devices (PHOLEDs) with Ir(piq)2acac as an emitter, DBTPC1 and DBTPC2 display maximum external quantum efficiencies (EQEs) of 18.8% and 13.2%, respectively. Experimental results demonstrate that DBTPC1 outperforms the commercial host CBP, making it a promising candidate for practical applications in red PHOLEDs and future exploration in multi-color PHOLEDs.

Carbazole or carbazole-3-carbonitrile/pyridine host materials for efficient solution-processable blue phosphorescent and green TADF OLEDs

Chao Tang, Jianmei Chen, Zhenghua Zhu, Changdong Shao, Yong Wang, Youhua Chen, Zijie Zhu, Mingxuan Shi, Yue Jin, Hui Yang, Jiujuan Fu, Yuxin Han, Jiayi Hu, Fangfang Wang, Jia Hu, Xudong Cao, Yuhe Kan, Lili Zhang

Summary: Two carbazole or carbazole-3-carbonitrile/pyridine-based bipolar materials were synthesized as hosts for solution-processed sky-blue PhOLEDs and green TADF-OLEDs. Increasing the doping concentration from 10% to 15% slightly reduced the turn-on voltage of the devices based on 2,6-CzPy. Introduction of cyano substituents improved the thermal stability of the hosts, but also resulted in deeper HOMO levels and larger hole injection barriers in CN-2,6-CzPy, which did not contribute to enhanced device performance.

Designing CMOS compatible efficient ohmic contacts to WSi2N4 via surface-engineered Mo2B monolayer electrodes

Liemao Cao, Xiaohui Deng, Zhen-kun Tang, Rui Tan, Yee Sin Ang

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Photoluminescence and structural phase transition relationship in Er-doped BaTiO3 model ferroelectric system

Jingye Zou, Shenglan Hao, Pascale Gemeiner, Nicolas Guiblin, Omar Ibder, Brahim Dkhil, Charles Paillard

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
