“…It is well known that a noble metal nanoparticle residing above a gold mirror or a dielectric substrate can generate strongly coupled plasmons and thus induce a larger near‐field enhancement contribution for SERS. Recently, a similar enhancement phenomenon has also been observed in reverse systems wherein semiconductor nanoparticles are deposited on the surface of a metal film . This is probably related to the perturbation of the metal surface medium, which is a consequence of a semiconductor‐induced change in the local dielectric constant or local refractive index.…”

Surface‐enhanced Raman scattering (SERS) is increasingly becoming an important analytical technique in various fields, which can mostly be attributed to the significant evolution of SERS‐active substrates. The semiconductor‐based SERS technique is particularly interesting because the inherent physicochemical properties of semiconductor materials offer several possibilities for the development and improvement of SERS‐based analytical techniques. According to the effect of the semiconductor materials in SERS, semiconductor‐based SERS techniques can be categorized into two areas: (1) semiconductor‐enhanced Raman scattering, in which a semiconductor material is directly used as a substrate for enhancing Raman signals of adsorbed molecules, and (2) semiconductor‐mediated‐enhanced Raman scattering, in which a semiconductor is employed as an ‘antenna’ or ‘trap’ to modulate the Raman enhancement originating from a metal substrate. While the theory on semiconductor‐based SERS is still incomplete and evolving, semiconductor‐based SERS techniques have already resulted in substantial progress in biological analysis, photocatalysis, solar cells, sensing, and optoelectronic devices. The aim of this review is to outline the recent progress in this emerging research field, with a special emphasis on its analytical performance and application areas.

Titanium dioxide (TiO 2 ) is an excellent candidate material for semiconductor metal oxide-based substrates for surface-enhanced Raman scattering (SERS). Biotemplated fabrication of TiO 2 thin films with a 3D network is a promising route for effectively transferring the morphology and ordering of the template into the TiO 2 layer. The control over the crystallinity of TiO 2 remains a challenge due to the low thermal stability of biopolymers. Here is reported a novel strategy of the cellulose nanofibril (CNF)-directed assembly of TiO 2 /CNF thin films with tailored morphology and crystallinity as SERS substrates. Polymorphous TiO 2 /CNF thin films with well-defined morphology are obtained by combining atomic layer deposition and thermal annealing. A high enhancement factor of 1.79 × 10 6 in terms of semiconductor metal oxide nanomaterial (SMON)-based SERS substrates is obtained from the annealed TiO 2 /CNF thin films with a TiO 2 layer thickness of 10 nm fabricated on indium tin oxide (ITO), when probed by 4-mercaptobenzoic acid molecules. Common SERS probes down to 10 nm can be detected on these TiO 2 /CNF substrates, indicating superior sensitivity of TiO 2 /CNF thin films among SMON SERS substrates. This improvement in SERS sensitivity is realized through a cooperative modulation of the template morphology of the CNF network and the crystalline state of TiO 2 .
