| Abstract: | The two-photon absorption that leads to the ultraviolet upconversion luminescence in the SiO2-Al2O3-B2O3-Na2O3-Zr2O: Cd3+ glass has been investigated. The inference has been made that no photon cascade emission takes place under excitation by monochromatic light corresponding to the maximum of the absorption band of the Cd3+ ion (204 nm). The mechanisms of concentration quenching and energy transfer between Cd3+ ions and optically active defects of the aluminoborosilicate glass have been discussed. |
