Oxygen can be removed from rock-salt structure of calcium oxide (band gap = 6.9 eV) by means of irradiation. The vacancies can be filled with either one electron ([F.sup.+]-centre) or two electrons (F-centre). These colour centres are produced by either particle bombardment or additive ...
Optical Band Gap Studies in Erbium Doped Calcium Aluminosilicate Glasses Containing a Small Amount of Silica 来自 知网 喜欢 0 阅读量: 42 作者:DB Zhang,JP Tang,ZP Liu,HU Li-Li 摘要: The relationship between the structure of the host glass and the properties of the doped ions is useful for...
However, the 2D nature of graphene inherently limits the sensor response because the one-atom thickness, high surface-to volume ratio and the zero band gap, makes highly difficult to switch the graphene into an electrically conductive “off-state”. In addition, the interaction between the ...
https://doi.org/10.3390/ ma14030604 Abstract: Gallium oxide (Ga2O3) is a promising wide-band-gap semiconductor material for UV optical detectors and high-power transistor applications. The fabrication of p-type Ga2O3 is a key problem that hinders its potential for realistic power applications....
The HPs have a high absorption edge compared to oxide perovskites (∼200 nm) and oxynitride perovskites (∼650 nm) [57]. The majority of organic and inorganic perovskites show a narrow band gap (≈1.5 eV) and great light absorption coefficient (≈105 cm−1). To enhance the optical ...
‘jGCaMP8’ sensors, based on the calcium-binding protein calmodulin and a fragment of endothelial nitric oxide synthase, have ultra-fast kinetics (half-rise times of 2 ms) and the highest sensitivity for neural activity reported for a protein-based calcium sensor. jGCaMP8 sensors will allow...
(Trueman1966), ions of calcium might be partially replaced by Sr, Ba, Mg, Mn, K, Na, Fe, while ions of hydroxide, chloride, bromide, carbonate and oxide may to a certain extent substitute fluoride in the crystal lattice of natural apatites (Pan and Fleet2002). Furthermore, organic ...

applications in different fields of great interest such as for instance catalysis, medication, agriculture, power storage, gasoline cells, detectors, electrochemical products and supramolecular chemistry.Multicomponent oxide microspheres with interconnected macroporosity (MICROSCAFS®) are brand new materials ...
Additionally, by controlling the weight percentage of doped silver, the band gap of calcium hydroxide nanospheres can also be controlled. By doping 0.6 wt% of Ag, 100% of MB dye can be degraded within 30 min. In addition, 0.6 wt% Ag-doped calcium hydroxide nanospheres exhibit photocatalytic ...
