High-Voltage, High-Current Electrical Switching Discharge Synthesis of ZnO Nanorods: A New Method toward Rapid and Highly Tunable Synthesis of Oxide Semiconductors in Open Air and Water for Optoelectronic Applications

“…55 The peaks positioned at 96 and 430 cm −1 (Figure 5a) belong to E 2 (low) and E 2 (high) modes, respectively, which confirm that the ZnO with a wurtzite structure has formed. 19 The intensity ratio of the 430 cm −1 to the 96 cm −1 peak of the sample 250-W-a has reduced compared to the other samples. The conclusion can be drawn that the crystal structures of the samples synthesized in air and those synthesized in water without annealing have better quality than the annealed samples synthesized in water.…”

Structural, Optoelectronic, and Electrochemical Properties of Zn1–x(Ga0.5Al0.5)xO Nanoparticles for Supercapacitor Applications

“…A weak peak appears at ∼380 cm –1 corresponding to an A 1 (TO) vibration . Accompanying closely at ∼ 405 cm –1 is the extremely weak E 1 (TO) . Compared to these modes, the E 2 high mode at around ∼437 cm –1 is extremely strong and is the main feature of the Raman spectra.…”

“…19 Accompanying closely at ∼ 405 cm −1 is the extremely weak E 1 (TO). 20 Compared to these modes, the E 2 high mode at around ∼437 cm −1 is extremely strong and is the main feature of the Raman spectra. This mode can be attributed to the lattice vibrations of the oxygen atoms.…”

Surface Coordination Layer to Enhance the Stability of Plasmonic Cu Nanoparticles

“…For Cu@Cu 2 O NPs, the Raman band at 712 cm –1 was attributed to the Cu–O stretching vibration (from Cu 2 O), meanwhile the band at 570 cm –1 was assigned to free absorbed oxygen (Cu–OH stretching). , In the case of Cu@Cu 2 O/ZnO, the Cu–OH stretching vibration band at 570 cm –1 disappeared when the surface coordination layer was formed on the Cu@Cu 2 O head . A new Raman peak at 413 cm –1 was observed (Figure S9), which was attributed to the Zn–O stretching vibrations Figure S10 displays the XPS survey scan spectra of Cu@Cu 2 O, ZnO, and the Cu@Cu 2 O/ZnO heterojunction.…”

“…18 A new Raman peak at 413 cm −1 was observed (Figure S9), which was attributed to the Zn−O stretching vibrations. 33 Figure S10 displays the XPS survey scan spectra of Cu@Cu 2 O, ZnO, and the Cu@Cu 2 O/ZnO heterojunction. The Cu@ Cu 2 O NPs showed two obvious O1s XPS peaks with a peak area ratio of 0.97 (Figure 5b, Table S1), in which the peak at 531.50 eV was from free absorbed OH − and the other peak at 530.40 eV was from O 2− on Cu.…”
