A standard test method for the determination of quantum efficiency (power output) of quantum dots and nano-phosphors is under development at RTI International for consideration by the U.S. Technical Advisory Group to IEC TC 113.  The result of this method will be that industries that use these nanomaterials can make reliable apples-to-apples performance comparisons of such materials.  However, it is especially important for solid-state lighting manufacturers, the end-users of nanoscale crystals, to be at the table during the development stages to ensure that the method produces meaningful results for their particular end-product application.  In general, U.S. lighting industry involvement through the TC 113 TAG, to set international standard performance and reliability assessments for nanoscale attributes, will help strengthen its competitiveness in the global marketplace for next generation lighting.
