Thin Film Fabrication and Exploring the Application of the Beer Lambert Law to Measure Thin Film Thickness

Abstract

Manipulation of the concentration of polymer host APC and the spin speed of a spin-coater organic thin films of Disperse Red or DR1 can be fabricated to around the thickness of .6 microns. Thickness measurements were achieved using a prism coupler. However the device’s limitations make it so it cannot be used to measure the thickness of thinner films. The Beer-Lambert Law was explored with the hopes of developing an alternative method of measuring film thickness.
