Tin (IV) Oxide, SnO2 nanoparticles

Tin oxide nanoparticles (SnO2) is a n-type semiconductor with a wide band range,  suitable for thin film engineering, functional coating applications. conductive inks as well as optoelectronic devices and solar cells.

We at Particular Materials synthesize nano (SnO2) and we produce and supply dispersions with excellent stability, monodispersity and fully disaggregated state.

Technical Information

SnO2 nanoparticles are extrinsic semiconductors where oxygen acts as the electron donor atoms. These electronically neutral molecules provide an excess of negative electrons to the crystal lattice of SnO2 nanoparticles.

This allows SnO2 to cover several functions in the electronic industry, such as:

  • Electron injection
  • Electron transport
  • Hole blocking
  • Charge recombination

 It′s unique characteristics such as low cost, high gas sensing abilities, low response time and fast recovery makes it a promising material for gas sensors.

Other important markets for tin dioxide are OLEDs, OPVs, Perovskite PVs, QLEDs and printed photodetectors.

Tin oxide nanoparticles have magnetic properties that allow their use in magnetic data storage and magnetic resonance.

In order to be able to take advantage of the various properties of Tin Oxide (SnO2) nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.

We at Particular Materials synthesize nano SnO2 and we produce and supply dispersions with excellent stability, monodispersity and fully disaggregated state.

The SnO2 nanoparticles are available in two different sizes:

  • 16 ± 4 nm
  • 40 ± 20 nm

Typical concentration in water are, by weight (w/w%):

  • 1%
  • 5%
  • 10%
  • 20%

SnO2 can also be provided as nanopowder.

Related Applications and Industries

  • Catalysts
  • Transparent heating elements
  • Anti-static coatings
  • Electrodes and antireflection coatings in solar cells
  • Gas sensors
  • Energy-conserving coatings
  • Optoelectronic devices
  • Resistors
  • Liquid crystal displays

A peculiar characteristic of all nanoparticles is the high surface area to volume ratio, that allows a considerably higher binding capacity and excellent dispersibility of NPs in solutions.
