Up till now, however, most of the reports of NPBSs are suitable for visible light.
Compared with (BiO 2CO3 (3.14 eV), the (BiO 2 CO3)x(I2)1−x solid solution showed narrowed band gaps from 1.89 to 2.68 eV which are suitable for visible light excitation.
Traditional methods (e.g., computed tomography and magnetic resonance imaging) can provide good imaging in the detection of tumors but are not suitable for visible detection of tumor cells during surgery.
ZnS has a larger band gap than that of ZnO (approximately 3.4 eV [17]), and therefore, it is more suitable for visible UV light-based devices such as sensors/photodetectors.
The coupling to BiOI with BiOCl led to down-lowered valence band (VB) and up-lifted conduction band (CB) in contrast to BiOI, making the composites suitable for visible light excitation.
The annealing at 1000 °C is suitable for visible emission in the PL spectra measured in 10 K on the BS prepared in vacuum (sample I), and the optimal annealing time is about 15 min at 1000 °C for visible emission in the PL spectra measured at room temperature on the BS prepared in oxygen of 80 Pa (sample II).
Certain properties of ZnS are unique and advantageous compared to ZnO, that is, ZnS has a larger band gap than ZnO (approximately 3.4 eV [17]), and therefore, it is more suitable for visible-UV light-based devices such as sensors or photodetectors.
This demonstrates that organic/inorganic film may be suitable for the visible electroluminescent emission of the top-emitting OLEDs.
First, is the Barringer remote sensing correlation spectrometer designed for the quantitative measurement of gases, such as nitrogen oxides or sulfur dioxide, in an optical path between the instrument and a suitable source of visible and ultraviolet radiant energy.
While the titania bandgap is not suitable for high visible spectrum efficiencies, the high photoconversion efficiency achieved under UV illumination indicates the suitability of the highly ordered nanotube-array architecture for hydrogen generation by water photoelectrolysis.
