Special Issue Information

Dear Colleagues,

Optoelectronic materials are often regarded as the cornerstone of the optoelectronic information industry. In recent decades, although significant progress has been made in the development of optoelectronic materials for various applications, the understanding and optimal design of high-performance optoelectronic materials still need to be improved in various specific applications. Recently, the emerging applications of nanostructures/nanomaterials in newly developed nanotechnology provide opportunities to significantly improve photoelectric performance by improving optical absorption, carrier separation and transfer efficiency. On the other hand, many new systems of optoelectronic materials have been developed, such as perovskite materials, organic–inorganic heterojunction, nano-photonics and semiconductor electrolyte junction. The organic combination of nanostructures/nanomaterials and new (or traditional) materials will greatly improve the performance of photoelectric materials. An important reason for this is that nanostructures/nanomaterials can significantly enhance light collection in a very small area, in which the transmission distance for photo-generated carrier extraction is very small, and the active sites for photo-generated carrier transfer are relatively dense.

In this Special Issue, we aim to provide a timely perspective on the advances in photoelectric materials and sensing applications. Topics to be covered include (but are not limited to):

  • The fabrication of nanostructures.
  • The optical properties of nanostructures.
  • Optoelectronic materials: fabrication and optoelectronic properties.
  • Sensing (refractive index sensing, optical fiber sensing, biosensors and so on).
  • Sensing under artificial intelligence.
  • Photocatalysis and applications.
  • Photoluminescence and devices.
  • The interaction between light and matter.

Here, we document a D-type double open-loop channel floor plasmon resonance (SPR) photonic crystal fiber (PCF) for temperature sensing. The grooves are designed on the polished surfaces of the pinnacle and backside of the PCF and covered with a gold (Au) film, and stomata are distributed around the PCF core in a progressive, periodic arrangement. Two air holes between the Au membrane and the PCF core are designed to shape a leakage window, which no longer solely averts the outward diffusion of Y-polarized (Y-POL) core mode energy, but also sets off its coupling with the Au movie from the leakage window. This SPR-PCF sensor uses the temperature-sensitive property of Polydimethylsiloxane (PDMS) to reap the motive of temperature sensing. Our lookup effects point out that these SPR-PCF sensors have a temperature sensitivity of up to 3757 pm/°C when the temperature varies from 5 °C to 45 °C. In addition, the maximum refractive index sensitivity (RIS) of the SPR-PCF sensor is as excessive as 4847 nm/RIU. These proposed SPR-PCF temperature sensors have an easy nanostructure and proper sensing performance, which now not solely improve the overall sensing performance of small-diameter fiber optic temperature sensors, but also have vast application prospects in geo-logical exploration, biological monitoring, and meteorological prediction due to their remarkable RIS and exclusive nanostructure.
