This current work revealed a single-step fabrication of tungsten oxide nanoflakes (WO3 NFs) with the help Terminalia arjuna bark extract. Bioactive phytoconstituents T. extract were involved in nucleation process and promoted material crystalline growth particular direction. The as-prepared sample thermal decomposition was analyzed by TG/DTG. annealed at 300 °C for 2 h, characterized UV-Vis-DRS...
