Aerogel-platform optical sensors for oxygen gas ...

· Aerogel-platform optical sensors for oxygen gas were constructed simply by entrapping three gas-sensitive probes within aerogel monoliths prepared via a rapid supercritical extraction method. The lack of a solvent-extraction step in this aerogel formation process facilitates the entrapment of probe species within the aerogel matrix. The three probes used in the work presented here, tris(2,2′ …

Optical Oxygen Sensors - PyroScience GmbH

An optical oxygen sensor basically comprises of two important parts: An oxygen sensitive sensor indicator and a read-out device ( oxygen meter). The oxygen meter consist of a LED and photodiode which excites the oxygen sensitive indicator and detects its oxygen dependent luminescence emission. The excitation and emission light is transmitted via an ...

Aerogel-platform optical sensors for oxygen gas ...

We have developed aerogel-platform gas sensors that respond rapidly to changes in oxygen concentration. The aerogels are prepared via a novel one-step supercritical extraction technique, which employs a metal mold and a commercial hydraulic hot-press. The lack of a solvent extraction step facilitates the entrapment of probe species within the aerogel matrix. The three probes used, tris(2,2 ...

It also has virtually no cross sensitivity, allowing it to be used in applications where other technologies are unreliable due to the particular mix of gases present. LuminOx measures the partial pressure of oxygen (ppO 2) which, along with the internal sensor temperature is communicated serially to the host microcontroller. LuminOx is also available with an internal barometric pressure sensor. This enables oxygen …

Transparent nanocolumnar porous ZnO thin films have been prepared by plasma-enhanced chemical vapor deposition. By controlling the H2/O2 ratio in the plasma gas, the deposition conditions were optimized to obtain an intense exciton emission at around 381 nm and virtually no luminescence in the visible region associated with electronic states in the gap.
