Impact of PEDOT:PSS/Ti3C2Tx composite hole transport layer on the performance of perovskite light emitting diodes
The two-dimensional transition metal carbide MXenes, often designated by Ti3C2Tx, have garnered significant interest on account of their distinctive optoelectronic characteristics. In this paper, PEDOT:PSS/Ti3C2Tx composite hole transport layer (HTLs) was prepared by adding the MXenes material Ti3C2Tx into PEDOT:PSS, and quasi-two-dimensional perovskite light-emitting diodes (PeLEDs) were fabricated and investigated. While the addition concentration of Ti3C2Tx was 0.25 mg/mL, the optimal device shows the maximum luminance of 6250 cd/m2, and the current efficiency of 6.17 cd/A, which is 133 % and 112 % higher than the reference device without Ti3C2Tx, respectively. It is indicated that the additive incorporation of Ti3C2Tx in PEDOT:PSS can improve the efficiency of hole injection and conductivity of hole transport layer, and passivate the defects of perovskite film, thus enhancing the optoelectronic performance of PeLEDs. The findings of this study indicate that the PEDOT:PSS/Ti3C2Tx composite HTLs has considerable potential for application in PeLEDs.
期刊介绍：
The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid.
We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
