Current Results (June 05)
Here are some of my results so far. This sample consist of
commercially available antimony doped tin oxide nanoparticles. As
you can see from the optical and AFM
images the quality of the films are pretty good, and more importantly
they are very porous. Also,
conductivity measurements does confirm that the films are in fact
conductive. The colored samples have been coated with a
Nanoporous Powder (NPP) Vapor
This project explores the viability of sol-gel derived
inorganic/organic composite nanoporous powders, doped with various
lumiphores as sensors. Thus far, a number of lumiphores have been
successfully incorporated into these powders and have shown potential
for the detection of methanol and ammonia vapors.
Challenges still remain though. For one, the ability
to undergo several sensing cycles, without degradation, needs to be
improved, and the sensitivity still needs to be worked on.
Here are some preliminary results so far.
