Controllable synthesis and morphology-dependent photoluminescence properties of well-defined one-dimensional Zn 2 GeO 4 :Mn 2+ nanostructures

Mn 2+ ‐doped Zn 2 GeO 4 for photocatalysis hydrogen generation

“…Zn 2 GeO 4 :Mn 2+ phosphors have been widely reported in recent years, which show green emission upon ultraviolet or near ultraviolet excitation and potential applications in white light emitting diodes and solar cells. [16][17][18][19][20] However, there are no reports about the influence of Mn 2+ doping on the photocatalytic activity of Zn 2 GeO 4 . It has been reported that Mn 2+ doping can enhance the photocatalytic activity, [21][22][23] 2 •4H 2 O were used as starting materials.…”

Luminescence properties in relation to controllable morphologies of Ba3[Ge2B7O16(OH)2](OH)(H2O):Eu3+ and its thermal conversion product Ba3Ge2B6O16:Eu3+

“…It is widely accepted that the luminescence properties of the phosphors are strongly dependent on the morphology, size, crystallinity, the center of luminescence and the density of defects. [18][19][20][21][22][23][24][25] The hexahedral-ake morphology of Ba 3 [Ge 2 B 7 -O 16 (OH) 2 ](OH)(H 2 O):Eu 3+ shows the shorter edge and thickness with a larger specic surface area than the rhombohedron-like morphology and the thorn-ball-like morphology, which can result in a high concentration of luminescence centers, causing enhancement of the emission intensity. 31,32 The photoluminescence decay curves of the samples with different morphologies Ba (1)…”

“…Therefore, the Zn 2 GeO 4 :Mn 2+ nanobundles exhibit broader diameters and larger particle size, which induces lower surface area and leads to fewer defects and stronger luminescence. 20 polyhedrontype particles, via a facile hydrothermal method. The inuence of the morphology and crystalline phase on the photoluminescence of Tb 3+ ions in the borate micro-nanostructures was investigated.…”

Quantum mechanical modeling of Zn‐based spinel oxides: Assessing the structural, vibrational, and electronic properties

“…In addition, as an essential wide band‐gap photocatalyst, Zn 2 GeO 4 has demonstrated superior activities for water splitting, degradation of pollutants, and photoreduction of CO 2 . [ 37–50 ] Moreover, the ability to modulate in vitro inflammatory mediators and in vivo acute inflammation of Mn‐doped Zn 2 GeO 4 was evaluated for the first time by V. Y. Suzuki et al [ 51 ]…”

“…In addition, as an essential wide band-gap photocatalyst, Zn 2 GeO 4 has demonstrated superior activities for water splitting, degradation of pollutants, and photoreduction of CO 2 . [37][38][39][40][41][42][43][44][45][46][47][48][49][50] Moreover, the ability to modulate in vitro inflammatory mediators and in vivo acute inflammation of Mn-doped Zn 2 GeO 4 was evaluated for the first time by V. Y. Suzuki et al [51] Zinc stannate (Zn 2 SnO 4 ) is an n-type transparent conducting oxide and was investigated as a transparent conducting oxide in electro-optical devices, owning to its optical transparency and electrical conductivity. [52] Its composition has higher electron mobility (10-30 cm 2 V −1 second −1 ), a wide optical band-gap of approximately 3.6 eV, and a relatively low refractive index of~2.0 in the visible spectrum.…”
