| titleOfInvention | A kind of photonic crystal sensor and its preparation method and application |
| abstract | The invention belongs to the technical field of heavy metal ion detection, and discloses a photonic crystal sensor and a preparation method thereof. First, an inverse opal photonic crystal with pH response is prepared; A sodium-acting photonic crystal sensor. Sodium sulfide is alkaline in aqueous solution, and the pH of water increases, which can stimulate the response of inverse opal photonic crystals with pH response, and the diffraction peaks of inverse opal photonic crystals undergo a red shift; when heavy metals are introduced into the solution system containing sodium sulfide ions, these heavy metal ions can be combined with S 2- or OH in the system to cause precipitation to make the solution system tend to be neutral, pH is reduced, and the diffraction peak of the inverse opal photonic crystal is blue-shifted. Therefore, the photonic crystal prepared by the present invention The sensor indirectly realizes the visual detection of heavy metal ions through the pH change produced by the precipitation of the heavy metal and sodium sulfide system. |
