Nanocomposites of carbon nanotubes and photon upconversion nanoparticles for enhanced optical limiting performance

Studies have proved that large nonlinearities, fast responses, and broadband spectra are pre-requisites for designing materials with good optical limiting performance. Carbon nanotubes (CNTs) have shown promising optical limiting effects with the best performance at 532 nm. However CNTs can only be...
