made of polycarbonate substrate membrane withnano-stripe
was used as photonic crystal sensor in this article. Spectral reflectance rate of this CD photonic crystal sensor rose from 64.5% to 99.1% linearly when temperature changed from 40 to 120℃
and the correlation coefficient
R
2
was 0.9995. Therefore
this CD polycarbonate membrane photonic crystal can be used as a temperature sensor. This sensor also was used as an organic alcohol sensor. The CD photonic crystal sensor was inserted into methanol and the experimental results showed that the maximum spectral reflectance rate reduced linearly with the reaction time. Other organic alcohols like ethanol
N-propanol and N-butanol all had the same linear tendency. The relation of dielectric constants of these organic alcohols and spectral reflectance rate reducing was linear relation too. All these means that this CD photonic crystal sensor also can be used as the tool of the detection of organic alcohol.
