Toward a New Era of SERS and TERS at the Nanometer Scale: From Fundamentals to Innovative Applications.
TL;DR: In this article , the authors report new directions and perspectives of SERS and TERS, mainly from the viewpoint of combining their mechanism and application studies, and discuss four main topics: (1) nanometer to subnanometer plasmonic hotspots for SERS, (2) Ångström resolved TERS; (3) chemical mechanisms, i.e., charge-transfer mechanism of sERS and semiconductor-enhanced Raman scattering; and (4) the creation of a strong bridge between the mechanism studies and applications.

Nanocrystals of Cesium Lead Halide Perovskites (CsPbX3, X = Cl, Br, and I): Novel Optoelectronic Materials Showing Bright Emission with Wide Color Gamut
Loredana Protesescu,Loredana Protesescu,Sergii Yakunin,Sergii Yakunin,Maryna I. Bodnarchuk,Maryna I. Bodnarchuk,Franziska Krieg,Franziska Krieg,Riccarda Caputo,Christopher H. Hendon,Ruo Xi Yang,Aron Walsh,Maksym V. Kovalenko,Maksym V. Kovalenko +13 more
TL;DR: The compelling combination of enhanced optical properties and chemical robustness makes CsPbX3 nanocrystals appealing for optoelectronic applications, particularly for blue and green spectral regions (410–530 nm), where typical metal chalcogenide-based quantum dots suffer from photodegradation.

Surface-enhanced spectroscopy
TL;DR: The surface-enhanced Raman scattering (SERS) effect was first discovered by Fleischmann, Van Duyne, Creighton, and Creighton as discussed by the authors, who showed that molecules adsorbed on specially prepared silver surfaces produce a Raman spectrum that is at times a millionfold more intense than expected.
