Nanoscale metallic nanoparticle arrays can create super high resolution holograms for information storage and 3D displays
Holograms made of tiny particles of silver could double the amount of information that can be stored in digital optical devices, such as sensors, displays and medical imaging devices. Researchers from the University of Cambridge have developed a new method for making multi-coloured holograms from a thin film of silver nanoparticles, which could greatly increase …
