Perovskite application developers

Established in 2018, Singapore-based Nanolumi develops perovskite-based quantum dots for the display industry.

Nanolumi's first product, the Chameleon Film, is a color-conversion film made from perovskite quantum dots. The company sells the final film directly to display makers.

In 2019 Nanolumi raised US$1 million in seed funding to accelerate its R&D and its sales and marketing activities. Nanolumi expects their products to be in commercially available consumer electronic devices by mid-2021.

UK-based Helio is developing both photoluminescent and electroluminescent perovskite-based materials for the display industry. It is a joint spin-off from both Oxford University and the University of Cambridge.

Helio aims to use its materials to improve the color performance and power efficiency of both LCD, OLED displays and MicroLED displays, using the high quantum efficiency, narrow emission spectrum and high absorption of perovskites.

In June 2020 we posted an interview with Helio's CEO, who discusses the company's technology and business.

Switzerland-based Avantama AG (previously called NanoGrade) is specialized in the development and supply of printable and coatable materials for the manufacturing of optical or electronic thin films. Avantam's materials are based on liquid formulations and inks containing semiconducting metal oxides or luminescent perovskite quantum dots.

Avantama’s QDs show several differences when compared to other commercial QDs (CdSe and InP): the chemical composition is based on metal halide perovskites such as e.g. CsPbBr₃, the QD color is mainly controlled by the chemical composition and not by the QD size, no additional inorganic shell is needed for high quantum efficiency and stability and more.

Avantama states that its metal halide perovskite QDs yield the highest possible quantum efficiencies of > 95% which will result in best peak brightness of LCD displays.
