Tunable 3D light trapping architectures based on self-assembled SnSe₂nanoplate arrays for ultrasensitive SERS detection

Abstract

We demonstrate tunable 3D light trapping (up to ∼96%) architectures based on the SnSe₂nanoplate arrays (NPAs)<italic>via</italic>self-assembled growth and high performance (EF: 6.33 × 10⁶, LOD: 1 × 10⁻¹²M) SERS substrates based on SnSe₂NPAs.
