Impact of Fabrication Processes of Small-Molecule-Doped Polymer Thin-Films on Room-Temperature Phosphorescence

The development of organic materials displaying room-temperature phosphorescence is a research field that has attracted more and attention in the last years. Most studies focus on designing or optimizing emitter molecules to increase phosphorescent performance host:emitter systems. Rarely, overall thin-film preparation routines are compared with respect their triplet-state luminescence yield. Herein, different film techniques investigated using very same molecule. A variation host polymer, post-annealing temperature, fabrication procedure evaluated obtained lifetime, photoluminescent quantum yield, phosphorescence-to-luminescence ratio. This study elaborates importance gathers concise set data which helpful anyone particular system.
