New simple synthesis route of GaN powders from gallium oxyhydroxide

GaOOH, and β- and γ-Ga2O3nanowires: preparation and photoluminescence

“…The photoluminescence (PL) properties of the GaOOH and (b-, g-) Ga 2 O 3 nanowires were well resolved into a few sharp peaks using a high-resolution synchrotron X-ray source. As compared to the previous studies of b-Ga 2 O 3 nanorods and nanowires, having a broad band emission covering from the UV to the visible region, 1,2,5,16,17,[26][27][28] our findings may provide a valuable reference for further understanding PL mechanisms.…”

“…It is worth noting that the PL spectrum of b-Ga 2 O 3 nanowires based on previous studies exhibited a broad band covering from the UV to the visible range. 1,2,5,17,[26][27][28] With the high-resolution synchrotron X-ray source employed in the present work, the blue emissions of the GaOOH and (b-, g-) Ga 2 O 3 nanowires could be resolved into a few sharp peaks, providing a valuable reference for further understanding the PL mechanisms involved.…”

Ga doped RGO–TiO2 composite on an ITO surface electrode for investigation of photoelectrocatalytic activity under visible light irradiation

“…The Ga-O stretching vibration absorption was observed at 468.16 cm À1 and it denotes a monoclinic Ga 2 O 3 structure. 29 A strong peak at 2358 cm À1 is due to adsorbed CO 2 molecules on the TiO 2 surface for atmospheric CO 2 .…”

Synthesis and properties of GaO2H nanorods

“…For the non-milled GaN powders, a prominent IR absorption around 570 cm À1 is present, and it corresponds to the transverse optical lattice phonon modes of GaN (E 1 (TO)=561 cm À1 ) in Fig. 5a [11]. From Fig.…”
