Scientists have harnessed the natural ability of wood to faintly glow to develop a new sustainable phosphorescent material that could potentially be used in a wide number of applications, from medical imaging and optical sensing to ‘glow in the dark’ dyes and paints.
An international team of researchers led by North East Forestry University (China) and the University of Bath (UK) investigated the natural phosphorescent properties of lignin, a major component of wood.
Room-temperature phosphorescence (RTP) is when a material absorbs energy with a short wavelength (such as UV light) and then emits it as visible light...
