Nanoco Group - Re: NANO Stream Log - Concerning the use of Cd...

Concerning the use of Cd QDs in solid state lighting, the information provided does not allow a conclusion that such an exemption would be justified at present. The consultants therefore recommend not granting an exemption for Cd in QD applications to be used in solid state lighting. It should however be noted that such an exemption may be regarded as relevant within the next few years. This recommendation is thus made in light of the current limitations to clarifying the necessity of such an exemption and is not to be understood as the consultants support or objection to future requests. For the application of Cd QDs in displays, the consultants recommend granting an exemption with the following wording: Cadmium in components for display lighting applications, containing downshifting cadmium based semiconductor nanocrystal quantum dots, where the cadmium per display screen area is limited to less than 0.2 ug/mm2 To expire 01.07.2017 This exemption is recommended for a shorter period than that applied for, in light of the understanding that applications resulting in reduction of Cd quantities as well as Cd free substitutes are in final stages of research.
