Nanoco signs cadmium-free quantum dot development agreement with Osram
Current methods for producing white light from a blue LED tend to produce light that is weak in red wavelengths, resulting in light that lacks warmth and fails to show true colours. Nanoco quantum dots have the potential to overcome these issues, which are limiting the widespread adoption of LEDs in certain general lighting applications.
Nanoco has been working with Osram under joint development agreements since 2011 with the objective of delivering LED lighting with superior performance characteristics. Considerable technical progress has been made to date in optimising the method for incorporating Nanoco’s cadmium-free quantum dots with blue LEDs. During this latest phase of work with Osram, which is for a 12-month period, it is intended to further the product development.
Michael Edelman, Nanoco’s Chief Executive Officer, said: "We have worked with Osram since 2011 and have made significant technical progress towards the development of an LED incorporating cadmium-free quantum dots and offering substantially improved colour performance."
The Osram announcement came in the same week that Nanoco Group Plc admitted the company’s full-year loss widened as some of its joint development agreements ended in 2013, and it spent more on the commercialisation of of the company’s quantum dots technology.
Nanoco claims to be in various stages of development with a number of display makers from South Korea, Japan, United States, China and Taiwan for televisions, monitors and tablets.
The group’s loss for the year ended July 31 increased to £9.06 million from £5.04m with revenues more than halving to £1.4m from £3.9m.
The AIM-listed company said last month it expected commercial production of its quantum dots to begin in the first half of next year at a plant in South Korea being built by its partner, Dow Chemical Co.
Nanoco expects initial commercial orders for quantum dots to be manufactured and delivered from its Runcorn, Cheshire facility until Dow’s commercial production plant comes on line in the first half of 2015.
