Microstructural and optical properties of SnO2–ZnSnO3 ceramics

Fabrication of a Selective Sensor Amplification Probe Modified with Multi-Component Zn2SnO4/SnO2 Heterostructured Microparticles as a Robust Electrocatalyst for Electrochemical Detection of Antibacterial Drug Secnidazole

“…It is worth highlighting that the mode with the highest intensity at 662 cm -1 can be attributed to the symmetric stretching of Zn-O bonds in the SnO4 tetrahedra of the inverse Zn2SnO4. The weak Raman band at 690 cm -1 can be assigned to the A2u mode, while the peak at 776 cm -1 can be attributed to the first order Eg (translational), A1g (symmetric Sn-O stretching), and B2g (asymmetric Sn-O stretching) active Raman vibrational modes of SnO2 [25][26][27]. All these Raman modes confirm that the ZTO/TO MPs exist exclusively in a heterostructure.…”

High transparent, low surface resistance ZTO/Ag/ZTO multilayer thin film electrodes on glass and polymer substrates

“…Raman peaks appearing at 309.9 cm − 1 and 366.2 cm − 1 can be attributed to E (LO) and A1 (LO) symmetries, respectively, in ZnSnO 3 whereas the peak at 776.4 cm − 1 is assigned to the B 2g (asymmetric Sn-O stretching) vibration modes of SnO 2 [36]. A broad Raman peak at 1094.3 cm − 1 is related to the SLG substrate [37]. According to the literature [36], ZnSnO 3 peaks are observed in Raman spectra of the samples grown at room temperature.…”

“…But the emission intensity of the SZQ composites shows an obvious increase with the introduction of ZnO QDs. The origin of the visible peaks is owing to the existence of oxygen vacancies and structural defects [21,22]. The obvious highest emission of SZQ1% at 526 nm result from the oxygen vacancies indicates its high oxygen vacancies concentration.…”
