Highly Sensitive

A highly sensitive surface plasmon resonance (SPR) sensor composed of a photonic crystal fiber (PCF) with the D-type structure is designed and analyzed by the full-vector finite element method (FEM). Indium tin oxide (ITO) is adopted as the plasmonic substance on account of the low cost and controllable infrared range (1500–2600 nm). By optimizing the structural parameters, the sensor shows a maximum wavelength sensitivity of 46,000 nm/RIU and average sensitivity of 13,166.67 nm/RIU for analyte refractive indexes between 1.355 and 1.385. This PCF combining a circular layout and D-type structure offers excellent sensitivity while the deposition and manufacturing complexity can be reduced. This sensor will possess an extremely expansive development space in the field of chemical analysis and environmental safety.

Indium tin oxide (ITO) nanoparticles (NPs) were prepared by a coprecipitation process from a mixed solution consisting of indium chloride and tin chloride. The surface plasmon resonance (SPR) absorption was studied under different calcinate atmospheres. The characteristics of the optical properties, especially the absorption of near-infrared (NIR) region was recorded by the UV-Vis-NIR absorption spectroscopy. The results show that the SPR absorption peak appears at 2500 nm under an oxidizing atmosphere (air) or at 1300 nm under a reducing atmosphere (a gas mixture of Ar and 5 vol% H2) when calcinated under a single atmosphere. There is no change in the plasmon frequency with the variance of calcinate temperatures and therefore no change in the free carrier concentration. However, when calcinated first at 600 °C under an oxidizing atmosphere and then reheated under a reducing atmosphere at different temperature, the SPR absorption peaks of the ITO NPs are at the range of from 1200 nm to 1430 nm, undergoing a blue shift as the reducing process temperature increases. The SPR absorption of the prepared ITO NPs is easily controlled by calcinate temperature under a process of calcination first under an oxidizing atmosphere and followed by under a reducing atmosphere.
