Photoluminescent materials are essential for numerous modern technologies - displays, solar cells, optoelectronic devices and sensors among them. However, most photoluminescent materials in use today rely on toxic metals and non-renewable resources. Now a team of Yale researchers led by first author Ho-Yin (Leo) Tse, and professors Julie Zimmerman and Paul Anastas has found a way to make photoluminescent solid-state emitters with lignin, a key component of wood, and a waste product in paper manufacturing. Safe and renewable, lignin may prove to have a glowing future in photoluminescent technology. Click here for more information!
