摘要：

When it mentions phosphor-converted(PC) light source, people would think of white or near-infrared light sources. In contrast, attention on the PC light sources at the other end of the spectrum-the shorter-wavelength ultraviolet region is absent. Taking into account the potential applications of ultraviolet light, the investigation of PC design as an alternative ultraviolet light source will be interesting. Here we introduce a concept of ultraviolet PC light source, in which the ultraviolet emission can be achieved upon a blue-light upconversion excitation. As a proof of concept, we demonstrate the PC design using an ultraviolet-B phosphor, Lu2Pr0.01Gd0.99Al2Ga3O12. Upconversion emission at 313 nm appears from the phosphor upon illumination with a 450 nm laser. Subsequently, we prepare a composite film using the phosphor, and build a transmissive remote phosphor light source. According to the emission and excitation features of the PC light source, we present an ultraviolet imaging demonstration. This study brings the PC light source to the ultraviolet region, which may offer a unique opportunity for some applications of optical tagging or indicator in bright environments. © 2021, Science Press.
