Abstract

Smart photoluminescent nanocomposite surface coating was prepared for simple industrial production of long-persistent phosphorescence and superhydrophobic wood. The photoluminescent nanocomposite coatings were capable to continue emitting light in the dark for prolonged time periods that may reach 1...
