Figure 5. (A) PL intensities of FL-doped WO3, FN-doped WO3, and bare WO3. (B) Normalized time-resolved photoluminescence (TRPL) of FL-doped WO3, FN-doped WO3, and bare WO3. PL and TRPL were measured under room-temperature conditions. Detailed experimental information is provided in the experimental section.
