About Avantama
Avantama AG, headquartered in Stäfa, Switzerland, develops and produces specialty nanoparticles, suspensions and formulations for electronic applications. The company was founded under the name NanoGrade and has been operating as an audited materials supplier for the electronics industry since 2016. Its material portfolio includes luminescent metal-halide-based perovskite quantum dots (e.g. CsPbBr3), cadmium-free quantum dots, semiconducting metal oxides as well as antimony-doped tin oxides (ATOx) and phosphors. Production is solution-processed for printable and coatable thin films up to multi-ton scale. Services include contract and joint development, customized nanoparticles and formulations for proof-of-concepts, as well as the sale of established dispersions via a webshop. Customer industries include display technology (LCD, OLED, MicroLED, QD-OLED), perovskite photovoltaics, sensor technology and printed electronics. In November 2024, Avantama sold its perovskite QD IP portfolio, including know-how and production equipment.

Materials and Processes
Perovskite quantum dots (metal-halide perovskites)
Luminescent quantum dots for color conversion in LCD, OLED and MicroLED displays with quantum efficiencies above 95%.
Cadmium-free quantum dots
According to the supplier, they redefine the display market with Rec.2020 compliance for LCD backlights.
Semiconducting metal oxides (solution-processed)
Solution-processable materials for optical and electronic thin films, among others for OLEDs.
Antimony-doped tin oxides (ATOx)
Chemically stable, conductive and transparent interfacial layers for perovskite solar cells.
Phosphors
For color conversion sheets in MiniLED backlights alongside quantum dots.
