ZnO nanoparticles obtained by hydrothermal method at low temperature

Improvement of the crystallinity and photocatalytic property of zinc oxide as calcination product of Zn–Al layered double hydroxide

“…These results showed that Zn-Al-NO 3 -LDH precursors started to transform to a ZnO phase at 200°C and higher. ZnAl 2 O 4 spinel is present in the samples Zn-Al-LDH-600°C, Zn-Al-LDH-800°C and Zn-Al-LDH-1000°C as observed by diffraction peaks at 2h = 31.4°, 36.9°, 44.8°, 49.1°, 55.7°, 59.4°and 65.3°, corresponding to the reflections from (2 2 0), (3 1 1), (4 0 0), (3 3 1), (4 2 2), (5 1 1) and (4 4 0) planes, respectively [19].…”

Luminescent properties and X-ray photoelectron spectroscopy study of ZnAl2O4:Ce3+,Tb3+ phosphor

“…Zinc aluminate (ZnAl 2 O 4 ) is a well known semiconductor with a wide bulk band gap of 3.5-3.9 eV [1][2][3][4][5][6]. It belongs to a class of mixed-metal oxides called the spinels which are commonly represented by a general chemical formula AB 2 O 4 where A and B are divalent (2+) and trivalent (3+) cations, respectively.…”

On structural, optical and dielectric properties of zinc aluminate nanoparticles

“…In addition to this, zinc aluminate is used as a catalyst support owing to its high thermal stability. Recently the optical properties of zinc aluminate is being investigated and it was reported that polycrystalline zinc aluminate has an optical bandgap nearly equal to 320 nm and is highly reflective at wavelengths less than 300 nm (Pandey et al 1999;Ciupina et al 2004). Thus zinc aluminate may find applications in optoelectronic devices operated in the ultraviolet region.…”
