ABSTRACT:
Transparent thin layer indium tin oxide was coated on
polyethylene tetraphetalate (PET) substrate by means of spin coating process
and its opto-electronic properties have been investigated. The surface treated
by pulse Nd-YAG laser. Pulse frequency, duration and energy were, 1000 Hz, 0.2
to 20 ms and 25 to 40 J respectively. The effect of treatment on
crystallization, optical properties and bonding processes of the thin layer was
investigated. The results show that ITO coated on flexible PET substrates is
conductive and transparent. The sheet transparency for a 350 nm thickness in
the visible range is more than 83.6%. Using Nd-YAG laser increased conductivity
by a factor of 100 times and causes higher bonding performances.
