||In this research, we design and make a narrow-band pass filter by using chitosan, an environment-friendly material as a spacer. Macleod software is used to find out the refractive index and extinction coefficient of the material, and then design narrow-band pass filters in visible light band. First, Ag film was deposited on a substrate by magnetron sputtering. Second, chitosan was spin-coated on the Ag layer. Last, Ag film was deposited on the chitosan layer. The thickness of the chitosan layer was controlled by different rotational speed. After the sample was completed, we compared with the original design and do the analysis.|
Chitosan is hygroscopic, so we placing the sample in different humidity environment and measuring the redshift. And then we calculate the changes of refractive index, thickness and sensitivity of chitosan.
