Photonic crystal (PhCs) based sensing technology has gained more and more attention
because of its obvious advantages in sensitivity, stability, security, miniaturisation, portability …

We present a short review of recent progress in the field of optical gas sensors based on
porous silicon (PSi) and PSi composites, which are separate from PSi optochemical and …

The lack of sensors for low cost, extensive, and continuous detection of vapor pollutants is a
serious concern for health and safety in industrialized urban areas. Colorimetric sensors …

A photonic crystal (PC) sensor that can selectively detect organic vapors through visual color
changes has been proposed. The sensor was fabricated by infiltrating a tetraphenylethene …

Xylenes are common aromatic volatile organic compounds, which can cause severe
environmental pollution and healthy issues. The current instrumental detection methods are …

It is shown that, along with the advantages, sensors based on porous silicon (PSi) have
disadvantages that inhibit their widespread use. The parameters of PSi which can affect the …
