Abstract

We synthesized concave twin ZnO microdisks, whose outer surfaces are entirely enclosed by high-energy facets. Different from hexagonal planar WGM microdisks, individual concave twin ZnO microdisks show Fabry-Pérot resonances and anisotropic photoluminescence properties at room temperature.
