Preparation of Polyimide/Zinc Oxide Nanocomposite Films via an Ion-Exchange Technique and Their Photoluminescence Properties
Figure 7
Room temperature PL spectra of (a) the bare PI film and the PI/ZnO composite films after thermal treatment at 350°C for (b) 3, (c) 5, and (d) 7 h. The zinc ion loading before thermal treatment is 3960 nmol/cm2.
