Template-Induced Growth of Sputter-Deposited Gold Nanoparticles on Ordered Porous TiO2 Thin Films for Surface-Enhanced Raman Scattering Sensors

“…With the accumulation of sputter-deposited Au clusters, the LSPR peaks become more and more obvious. The red shift of the local decrease in reflectivity is mainly ascribed to a shifting of the LSPR of the deposited Au clusters growing in size and changing in shape during the sputter deposition process. , The absorption peak of the TiO 2 substrate is located in a wavelength range below 350 nm and thus is not observed in the spectra. , In particular, Au/TiO 2 nanocomposites have been regarded as one of the most promising substrates for SERS applications. ,,− We measure the SERS spectra of the R6G molecules adsorbed on the surface of these sputter-deposited ordered Au/TiO 2 nanohybrid thin films, as shown in Figure b. For the Au/TiO 2 nanohybrid thin films with δ Au = 2.2, 3.4, 4.5, and 5.6 nm, the characteristic SERS bands for R6G located at 1310, 1365, 1508, 1575, and 1648 cm –1 are observed, corresponding to the aromatic C–C stretching modes of the R6G molecule.…”

Review—Recent Progress in Low Temperature Synthesis of Crystalline TiO2 Photocatalytic Films by Highly Controllable Electrodeposition

“…Ertekin et al produced crystalline titanium suboxides (TiO x ) on ITO substrates by cathodic electrodeposition at room temperature from an alkaline acetonitrile solution containing titanyl sulfate (TiO(SO 4 )) and tetra n-butyl ammonium hydroxide (C 16 H 37 NO). 73 Phases of β-Ti 3 O 5 , λ-Ti 3 O 5 , ɣ-Ti 3 O 5 and Ti 4 O 7 were obtained between −1.2 and −2.0 V (vs Ag/AgCl), each displaying oxygen deficiencies compared to stoichiometric TiO 2 , which is due to water insufficiency in the acetonitrile solvent. Although there is no investigation on photocatalytic activity for the degradation of organic pollutants, the brownish coatings exhibited E gaps between 1.32-1.31 eV and a promising long-term stability of one year under aerial conditions.…”

Long-term heat-storage materials based on λ-Ti3O5for green transformation (GX)

“…The future memory density is expected to achieve one terabit inch À2 . The vast potential of l-Ti 3 O 5 has attracted many researchers: various synthesis methods have been developed, [36][37][38][39][40][41][42][43][44][45][46][47][48][49] studies of phase transition mechanism have been reported, [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] and novel functionalities are being explored. [67][68][69][70][71][72][73][74][75][76] Since l-Ti 3 O 5 is composed of readily available elements of titanium and oxygen, it offers harmless, sustainable, and economic features, which are advantageous in industrial applications.…”
