Ultraviolet organic light-emitting devices (UVOLEDs) are expected to develop into compact, environmentally friendly and large-size ultraviolet light source applications in analysis, information storage, display, biomedical, etc. However, most of the UV emitted organic materials have broad emission spectra, and thus the electroluminescence (EL) spectra of the most reported UVOLEDs have non-ignorable visible light components, which limits the application prospect of UVOLEDs.
