Nanoco Welcomes Recommended Short Exemption For Cadmium Quantum Dots(Alliance News Via Acquire Media NewsEdge) LONDON (Alliance News) - Nanoco Group PLC Thursday welcomed a report from the European Commission that recommends a temporary exemption of the Restriction of Hazardous Substances Directive to use cadmium-containing quantum dots in displays. The exemption is recommended to run to July 1, 2017. Quantum dots are nanocrystals made of semiconductor materials, which can be used in solar cells, LEDs and diode lasers. Nanoco produces quantum dots that do not contain cadmium - a heavy metal that is restricted under European and other territories environmental legislation. The report said that the exemption was for a shorter period than had been applied for by companies, as products with reduced cadmium or cadmium free substitutes were in "final stages of research." It has not recommended an exemption for the use of cadmium-containing quantum dots in solid state lighting. "This recommendation [...] recognises that cadmium is a hazardous substance and that Nanoco has developed a cadmium-free alternative on the threshold of commercialisation," said Chief Executive Michael Edelman in a statement. Shares in Nanoco were trading down 0.3% at 98.75 pence Thursday afternoon. Copyright 2014 Alliance News Limited. All Rights Reserved. |
