Breakthrough in multiphoton upconversion with increased energy conversion efficiency

Description

In the world of nanomaterials, when the “upconversion luminescence” material is excited by low-energy light, it can emit high-energy light, such as ultraviolet light. However, the emission intensity is not satisfied and hence limiting the further applications in different fields. A research team jointly led by the Materials Science and Engineering and Physics departments of City University of Hong Kong (CityU) has proposed a new strategy and successfully achieved upconversion luminescence with high energy conversion efficiency. The team believes that the research result will help further development and applications in miniaturized optoelectronic devices.
