The principle of measurement for UV-Visible Spectroscopy or UV-Visible spectrophotometer is relatively straightforward and consists of a light source, a wavelength dispersive element, sample, and detector.Figure 1. A basic block diagram of the elements in a single beam UV-Visible spectrometer.UV-...
371, 476 nm for different immersion durations respectively, in the visible region of the electromagnetic spectrum. The scanning electron microscopy (SEM) study illustrated that with increasing the immersion time, especially at 45 s, a change in the particle morphology was observed (LiNbO3NRs structur...
One of the very popular optical instruments is the UV-visible (UV-Vis) spectrophotometer, which is exten- sively used to measure the absorption spectrum of samples in the UV and visible regions. In our previous work11–15, we demonstrated photocatalytic planar microreactors (typical dimensions 5...
