aThe light-emitting plate is simple to fabricate. The light-emitting plate can emit high power and quality white light with controllable wavelength. The light-emitting plate is solid and robust. The configuration of the light-emitting plate enables fabricating white LEDs in large series, in an in...
which is where a crystalline substance is overlaid onto a substrate, resulting in a sheet of high quality graphene. They then excited the graphene with pump laser (1.55 eV.) pulses of very short duration (35 fs). In measuring the amount of light that was reflected back, they found it ...
