Setting up the auto-pipetter to dispense 1200ul.

Toluene being deposited in a vial with PFO-RED.

The solution is heated at 80C for about an hour. Inside the vial is a small magnetic rod, controlled by a circular array of electromagnets underneath the hot plate. This spins the vial, stirring the solution at high speed, under heat.

This is MEH-PPV, a green light emitting polymer. I'll use this to make a green OLED.

First I spin coat PEDOT:PSS - this is a solution of Poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) gel particles suspended in DI water. It's complicated stuff, but PEDOT:PSS makes for brighter, more efficient OLED devices.

A generous amount of PEDOT:PSS is applied to the anode side to be spin coated. I think I bought my spin coater from senz-it. It was cheap on ebay...

Spin time and speed are set.

The anode side now consists of the ITO-conductive electrode that was pre-deposited on the glass, as well as a layer of PEDOT:PSS for the hole transport layer (HTL).

This is the cathode slide, that hasn't been spun coat at all. It only consisted of an indium-tin oxide coating to make it conductive. Here, the cathode for the device is added. This is usually a low work function metal. Most low work function metals that are not alloys have a high melting point and are difficult to coat without a sputter coater or electron gun. So I'm using a liquid alloy consisting of indium, gallium, and tin. This is the metal droplet on the glass slide.
