a Phosphorescence spectra of water-fumed DPP-BOH-PVA film after heating at different temperatures for 15 min. b Time-resolved emission-decay profiles of water-fumed DPP-BOH-PVA film after heating at different temperatures for 15 min. c Phosphorescence spectra of desiccative DPP-BOH-PVA film under water fuming for different times. d Repeated cycles of the heating/water fuming processes and the corresponding photographs of DPP-BOH-PVA film after turning off the UV irradiation. e Photographs of water-fumed DPP-BOH-PVA film after heating at different temperatures (30 °C–80 °C). The temperature gradient was 10 °C and the corresponding heating time was 15 min, after which the RTP behaviors were studied when the samples were cooled to room temperature.
