Defective nanotubes turned into light emitters
Biscay, Spain (SPX) Nov 05, 2013
UPV/EHU-University of the Basque Country researchers have developed and patented a new source of light emitter based on boron nitride nanotubes and suitable for developing high-efficiency optoelectronic devices. Scientists are usually after defect-free nano-structures. Yet in this case the UPV/EHU researcher Angel Rubio and his collaborators have put the structural defects in boron nitride nanotubes to maximum use. The outcome of his research is a new light-emitting source that can easily be incor ... read more
