Enhanced Raman scattering from cesium suboxides in photocathodes: Ag―O―Cs (S-1) and Bi―Ag―O―Cs (S-10)

Raman spectra from photomultipliers having Ag–O–Cs photocathodes (S-1) are found to correspond to the vibrational spectrum of Cs11O3. The wavelength dependence of the Cs11O3 Raman intensity is compared with the radiant sensitivity of the S-1 photocathode, and the possible role of Ag islands in enhan...
