Optical properties of nanoparticles thin film in organic light emitting diode (OLED) / Siti Munirah Che Noh

In-depth study on silver nanoparticles (Ag) has been conducted through UV-Visible (UV-Vis) spectroscopy, atomic force microscopy (AFM), field emission scanning electron microscopy (FESEM), and current-brightness-voltage (IVL) measurement. A thin layer of silver nanoparticles was produced by depositi...
