Phonon-assisted anti-Stokes excitation of the fluorescence of Mn²⁺ ions in the CsMnCl₃ ּ 2H₂O crystal
We demonstrate that anti-Stokes excitation of Mn²⁺ ions in the CsMnCl₃⋅2H₂O crystal can occur through multiphonon addition to the energy of the photons of exciting light. The deficit dE between the energy of the Mn²⁺ ⁴T₁ exciton and the photon energy of the He–Ne laser used as the source of illumin...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | We demonstrate that anti-Stokes excitation of Mn²⁺ ions in the CsMnCl₃⋅2H₂O crystal can occur through multiphonon addition to the energy of the photons of exciting light. The deficit dE between the energy of the Mn²⁺ ⁴T₁ exciton and the photon energy of the He–Ne laser used as the source of illumination is compensated by simultaneous annihilation of several thermally activated lattice phonons. The absence of two-photon activation of the fluorescence was verified by measurement of the dependence of the fluorescence intensity on the intensity of the exciting light, which appears linear at a fixed energy mismatch dE. |
