As shown in Figure , the EL shows a dominant peak at 399 nm with a FWHM of 14 nm. We also conducted a detailed analysis of the EL spectra of devices over time, employing a constant current bias of 10 mA/cm² in an ambient atmosphere. The results, depicted in Figure , show that the EL spectra remains stable throughout the measurement duration, indicating consistent emission characteristics under the given operational conditions. However, a critical aspect noted in our observations is the limitation of device operational lifetime, as evident from the T50 value being less than one second (refer to Figure ). This short operational duration emphasizes the necessity for further research focused on enhancing UV PeLED operational stability. Figure presents a comprehensive overview of the performance benchmarks for solution processed violet PeLEDs reported to date. This work demonstrates the emergence of emissive perovskites for the ultraviolet regime, highlighting the potential of wide bandgap perovskite materials. Notably, this advancement also delivers an external quantum efficiency (EQE) that is highly competitive with the best-performing violet-emitting PeLEDs.
