1.        Ö÷ÓïΪelctrons, ionsΪÖ÷
Under the 808nm laser pump, the electrons of the Ho3+ ion transits from the ground state to the 4I9 / 2 energy level, and then to the 5I5 level via the non-radiative transition. When the electrons are excited by the 808nm photons again, they transits from the 5I5 to the 5G5 level. At this time, a part of the ions transits to the ground state via radiative transition, which produces 425nm purple upconversion. The left ions transit to the 5F3, 5F4, and 5S2 levels via a set of quick non-radiative transitions. Finally, the electrons transit to the ground state from the 5G5£¬5F3£¬5F4 and 5S2 levels via radiative transitions, and simultaneously produce the 486nm, 561nm and 656nm upconversion, respectively.
2.        Ö÷ÓïÒÔelectron energy levelΪÖ÷
Under the 808nm laser pump, the electron energy level of the Ho3+ ion transits from the ground state to the 4I9 / 2 level (or level 4I9 / 2), and then to the 5I5 level via the non-radiative transition. When the electrons are excited by the 808nm photons again, the energy level transits from the 5I5 to the 5G5 level. At this time, the energy level of a part of the ions transits to the ground state via radiative transition, which produce 425nm purple upconversion. The energy level of the left ions transits to the 5F3, 5F4, and 5S2 levels via a set of quick non-radiative transitions. Finally, the energy level transits to the ground state from the 5G5£¬5F3£¬5F4 and 5S2 levels via radiative transitions, and simultaneously produce the 486nm, 561nm and 656nm upconversion, respectively.
