SERS: Materials, Applications, And The Future
The classic SERS substrates of gold (Au), silver (Ag), or copper (Cu). In general, Au and Ag are most often used as SERS substrates because they are air stable materials, while Cu is more reactive. All three metals have LSPRs that cover most of the visible and near infrared wavelength range, ... Access Doc

XPS Spectra - Casaxps.com
The underlying assumption when quantifying XPS spectra is that the number of electrons recorded is proportional to the number of atoms in a given state. The basic tool for measuring the number of electrons recorded for an atomic state is the quantification region. Figure 8 illustrates a survey spectrum where the surface is ... Access Full Source

Color Of Chemicals - Wikipedia
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. What is seen by the eye is not the color absorbed, but the complementary color from the removal of the absorbed wavelengths . ... Read Article

Covered with gold foil. The output of the MCA shows the full spectrum of pulse heights, 0-5V (and thus the spectrum vs alpha particle energy). Little of the PMT noise is seen (note the discriminator on the MCA was set to reject pulses less than about 300mV), and in the middle is the spectrum due to detected alphas. ... Fetch Content
