Abstract

Surface plasmon polariton (SPP) lasers have so far relied on metallic substrates. Here, we report a three-dimensional (3D) plasmonic particle laser using gold coating on lead halide perovskite crystals as small as 620 nm in size. Upon optical pumping, SPP modes are strongly confined along the particle edges with high Purcell enhancement in room conditions. Lasing of metal-coated plasmonic laser particles in live cells is demonstrated.
