“The photo response time is about three orders of magnitude faster than a typical video refresh rate,” he said. “These LEDs can turn on and off so fast your eyes can’t tell. Nanorods, along with other noble metal nanoparticles, also function as theragnostic agents. Nanorods absorb in the near IR, and generate heat when excited with IR light. This property has led to the use of nanorods as cancer therapeutics. Nanorods can be conjugated with tumor targeting motifs and ingested. In GaN nanorod based LEDs for solid state lighting application, a regular arrangement of GaN nanorods will be beneficial for device processing and therefore be the basis for chip fabrication.
