A method applying a circular photonic crystal structure to improve optical properties of a photoelectric conversion device such as a light emitting diode device, an organic light emitting diode device or a solar cell is provided, wherein the circular photonic crystal structure is configured on a junction surface between two different mediums where passes a light emitted or received by the photoelectric conversion device. The circular photonic crystal structure provides isotropic photonic band gap which conduces high light extraction efficiency.

Disclosed is a trace detection device of a biological and chemical analyte, including a metal substrate, a periodic metal nanostructure on the metallic substrate, a dielectric layer on the periodic metal nanostructure, and a continuous metal film on the dielectric layer. Tuning the thickness of the dielectric layer and/or the continuous metal film to meet the laser wavelength can shift the absorption peak wavelength of the sensor, thereby further enhancing the Raman signals of the analyte molecules.
