My sample is a solid, so a film of dye coated on a microscope slide. Thats all it is. While getting the spec data, I place the dye coated slide right on the beam path against the cuvette holder. Is that something that affects the data I get?

Kevin, yes I did zero the spectrophotometer, and the sol I used is made up of : Tetraethyl orthosilicate, Ethanol, hydrogen phosphate and water.

Hello all, I am working on a dye doping project and got a photospectrometry result as show in a picture for my thin film. Can anyone please help me interpret the physical meaning of the graph below? Thanks!
