Fig. 4

a Normalized steady-state photoluminescence (dotted lines) and phosphorescence (solid lines) spectra of FA/PVA (top), PXZA/PVA (middle) and NTIA/PVA (bottle). Insets show the corresponding photographs of films taken before (left) and after (right) the ultraviolet source switching off. b The CIE coordinate diagram for the UOP colors of FA/PVA, PXZA/PVA and NTIA/PVA. c Phosphorescence lifetimes and efficiencies of FA/PVA (left), PXZA/PVA (middle) and NTIA/PVA (right). d Excitation-phosphorescence mapping of FA (top), PXZA (middle) and NTIA (bottom) in PVA film.
