Abstract
A silicon-nanocrsytal resonant-cavity light-emitting device (RCLED) is presented. The microcavity, made by a silicon nanocrystal layer inserted between a semitransparent Au reflector and a distributed Bragg reflector mirror, shows enhanced emission intensity by four times at resonance wavelength and 1/8 narrow emission spectrum compared to nonresonant devices. The external quantum efficiency and power conversion efficiency also increase by 3.5 times. Multiple colors, green, green-yellow, orange, and red are displayed by adjusting the cavity length of RCLED. © 2012 American Institute of Physics.
