Abstract
The invention subject of the present application generally concerns photoluminescent sensor devices for detecting a change in a gaseous environment.
Claims19
A sensor array comprising a plurality of substantially dry or water-free sensor devices for simultaneous sensing of multiple volatile compounds (VC) or mixtures thereof present in a gaseous environment, wherein each of the sensor devices comprises a light responsive surface comprising a substantially dry material-wrapped single walled carbon nanotube (SWCNT), each of the sensor devices being configured and operable for allowing a dry or water-free interaction, during operation of the sensor devices for sensing the at least one VC in the gaseous environment, between the at least one VC in the gaseous environment and the substantially dry or water-free SWCNT and/or the material wrapping same;
- and for emitting NIR photoluminescence indicative of said interaction.
An optical sensor device for determining presence of at least one volatile compound (VC) in a gaseous environment, the device comprising a light responsive dry or water-free surface comprising a water-free material-wrapped single walled carbon nanotube (SWCNT), the device being configured and operable for allowing in a dry state interaction, during operation of the sensor device for sensing the at least one VC in the gaseous environment, between the at least one VC in the gaseous environment and the SWCNT and/or the material wrapping same;
- and for emitting NIR photoluminescence indicative of said interaction, wherein the device is substantially water free, or adapted for operation in a substantially dry form.
