Spin Coating of PVA/Ru Thin Film on ITO Glass Slides with Ellipsometry Analysis and Lab Report
Oct 2019 – Nov 2019
Project description
In this experiment, multiple organic light emitting devices (OLEDs) were fabricated with
varying film thickness. The film was spin coated with a polyvinyl alcohol (PVA) and
ruthenium(II) complex solution onto an Indium Tin Oxide (ITO) glass substrate. The difference
in film thickness, caused by the varying spin coating speeds, was analyzed by ellipsometry. We
found that with an increase in thickness of films causes higher working voltages, while OLEDs
with thinner films had lower working voltages. We also found that the average duration of light
emittance was longer with thinner films.
