Surface‐enhanced Raman spectroscopy (SERS) is an ultrasensitive surface analysis technique that is widely used in chemical sensing, bioanalysis, and environmental monitoring. The design of the SERS substrates is crucial for obtaining high‐quality SERS signals. Recently, two‐dimensional transition metal dichalcogenides (2D TMDs) have emerged as high‐performance SERS substrates due to their superior stability, ease of fabrication, biocompatibility, controllable doping, and tunable bandgaps and excitons. In this review, we provide a systematic overview of the latest advancements in 2D TMDs SERS substrates. This review comprehensively summarizes the candidate 2D TMDs SERS materials, elucidates their working principles for SERS, explores the strategies to optimize their SERS performance, and highlights their practical applications. We particularly delve into the material engineering strategies, including defect engineering, alloy engineering, thickness engineering, and heterojunction engineering. Additionally, we discuss the challenges and future prospects associated with the development of 2D TMDs SERS substrates, outlining potential directions that may lead to significant breakthroughs in practical applications.This article is protected by copyright.

Field emission finds a vital space in numerous scientific and technological applications, including high‐resolution imaging at micro‐ and nano‐scales, conducting high‐energy physics experiments, molecule ionization in spectroscopy, and electronic uses. A continuous effort exists to develop new materials for enhanced field emission applications. In the present work, two‐dimensional (2D) well‐aligned CdSSe flake flowers (CdSSe‐FFs) were successfully grown on gold‐coated silicon substrate utilizing a simple and affordable chemical bath deposition approach at ambient temperature. The time‐dependent growth mechanism from nanoparticles to FFs was observed at optimized parameters such as concentration of precursors, pH (~11), deposition time, and solution temperature. The crystalline nature of CdSSe‐FFs is confirmed by high‐resolution transmission electron microscopy (HRTEM) results, and selected area electron diffraction (SAED) observations reveal a hexagonal crystal structure. Additionally, the CdSSe‐FFs thickness was confirmed by TEM analysis and found to be ~20–30 nm. The optical, photoelectric, and field emission (FE) characteristics are thoroughly explored which shows significant enhancement due to the formation of heterojunction between the gold‐coated silicon substrate and CdSSe‐FFs. The UV–visible absorption spectra of CdSSe‐FFs show enhanced absorption at 700 nm, corresponding to the energy band gap (Eg) of 1.77 eV. The CdSSe‐FFs exhibited field emission and photosensitive field emission (PSFE) characteristics. In FE study CdSSe‐FFs shows an increase in current density of 387.2 μ A cm−2 in an applied field of 4.1 V m−1 which is 4.08 fold as compared to without light illumination (95.1 μ A cm−2). Furthermore, it shows excellent emission current stability at the preset value of 1.5 μA over 3 h with a deviation of the current density of less than 5% respectively.Research Highlights Novel CdSSe flake flowers were grown on Au‐coated Si substrate by a cost‐effective chemical bath deposition route. The growth mechanism of CdSSe flake flowers is studied in detail. Field emission and Photoluminescence study of CdSSe flake flowers is characterized. CdSSe flake flowers with nanoflakes sharp edges exhibited enhanced field emission properties.
