·After
the thin films are dry, the lamp needs a power source.
·Copper
tape is used to make good contacts without damaging the lamp.
-Small
pieces of tape are attached to the ITO layer and the silver layer separately.
·The
phosphor requires a changing electric field in order to fluoresce.
-A
DC voltage will only produce a changing electric field in a capacitor as it
charges.
-In
order to produce continuous lighting an AC voltage is required.
·Normal
110V 60Hz AC power can be used to light your lamp. In
the lab we use a high frequency power supply 60-2000 Hz and a few hundred volts, which gives a brighter
light.
