Three and five layers of synthesized and commercially available of MEH‐PPV thin films were prepared by spin coating technique. Toluene was used to prepare the MEH‐PPV solutions and the solutions were deposited onto glass substrate. The optical properties and surface morphology of MEH‐PPV thin films were studied. Maximum absorption band of synthesized MEH‐PPV and commercially available MEH‐PPV was found around 505 nm. The absorption value for 5 layers is higher than 3 layers thin films. The optical band gap slightly increases with increasing the thickness of thin films. Surface morphology shows that the MEH‐PPV doesn’t disperse and dissolve well in solvent.
