ZnO films were fabricated on polyether sulfone substrates using gas-assisted liquid phase deposition with ethylene glycol (EG) at 60 degrees C. Water and NH3 vapors diffused from a water/EG/hexamethylenetetramine solution into a Zn(NO3)(2)/EG solution. This caused heterogeneous nucleation at the solid-liquid interface, which resulted in the formation of ZnO films. The ZnO films had a continuous film structure because of EG adhesion, and they exhibited visible light transmittance greater than 60%.
