Isabella got funding for additional 12 months from Fininsh Cultural Foundation, Varsinais-Suomi Regional fund for her research in the manufacturing of tenebrescent and persistent luminescence materials. Congratulations, Isabella!
Our latest publication enlightens an alternative route to prepare white emitting phophors by using Li-Hackmanites as a host material. Moreover, the long lasting persistent luminecence can be obtained without heavy metals.
Check out the publication in Advanced Functional Materials below and congratulations to Isabella, José and Mika for their hard work that really paid off!
