The authors observe more than six-fold enhancement of emission from CH3NH3PbI3 by employing surface plasmon (SP) in Au films. The enhancement mainly results from the increased radiative recombination rate via SP-coupling, with a small contribution from the back-reflection of Au. The SP-coupling technique is found to be more effective for CH3NH3PbI3 with relatively low quantum efficiency. This property leads to the homogeneous luminescence from inhomogeneous CH3NH3PbI3 samples. The SP-coupling technique thus provides a promising solution for super bright, high-speed, and large-area perovskite-based light emitting devices. Published by AIP Publishing.
