Customized Nanoparticles and Rapid Synthesis of New Nanoparticle Compositions
Written by AZoNanoJul 19 2013
Avantama’s range of products includes simple or complex oxide nanoparticles, advanced metal salt nanoparticles or doped nanoparticles (metal oxide and metal salt nanoparticles) which are produced according to individual specifications and in any composition. It is possible to order the desired compositions on their web shop in a fast and efficient way. Each customer can define the exact composition he desires and order the samples online.
Avantama nanoparticles are typically 10 to 50nm in size, and are characterized by extraordinary stability and chemical purity. Typical examples are applications such as antimicrobials, lasers and catalysts. The crystal phase of compositions can be adapted in many cases. If required, the Avantama nanoparticles can also be formulated into a nanoparticles ink, suspension or dispersion.
Vanadium Oxide (V2O5) Nanoparticles – Properties, Applications
Written by AZoNanoJun 25 2013
In the recent years, scientists have intensified their research in the field of nanoparticles mainly due to the innovative and unexpected results that are achieved through altering the atomic and molecular properties of various elements. This article looks into the properties and applications of vanadium oxide nanoparticles.
Vanadium forms a number of different compounds with oxygen, depending on the oxidation state of the vanadium metal. The most common of these are listed below - other stoichiometries can be found in vanadium oxide crystal phases in addition to these.
Vanadium (II) oxide (vanadium monoxide), VO
Developing and Producing Specialty Materials for Printed Electronics
Written by AZoNanoDec 18 2015
The field of printed electronics continues to advance at an impressive rate with new applications such as printed organic light emitting diodes (OLEDs), organic photovoltaic cells (OPVs), printed batteries and even micro printed sensors and electronic paper.
All of these concepts are essential to the development of thinner, lightweight more powerful hand held devices, new display technology and even personal and wearable electronics.
Avantama is preeminent in the development and production of specialty materials for printed electronic components. Based in the technology corridor adjacent to Lake Zurich, Avantama has created a range of metal oxide and semiconducting nanoparticles and has formulated them into inks ideal for printing electronic components. In addition, by optimizing their inks to industrial printing/coating systems their materials yield high quality opt
Buffer Layer Nanoparticle Inks for Printed Electronics

Printed electronic devices consist of multiple layers of functional materials. Each of these materials must be optimized to both perform well in the device, and to be printed as easily as possible. Other factors such as interactions between layers must also be taken into consideration.
Custom nanoparticle inks, such as those available from Avantama, are ideal materials for printed electronics. Avantama’s expertise in materials development can help with the creation of the ideal functional materials for printed devices.
The hole transport layer (HTL) must ensure good transport of holes between the active layer and the electrode whilst blocking electrons, whereas the electron transport layer (ETL) ensures an efficient electron transport whilst blocking holes. State-of-the art materials include organic PEDOT-PSS as HTL and e.g. vacuum-processed zinc oxide (ZnO) as ETL.
