Ho3+離子核外電子在808nm激光泵浦下從基態(tài)躍遷到4I9/2能級(jí)，再經(jīng)過(guò)無(wú)輻射躍遷到5I5能級(jí)。電子在808 nm光子的再次激勵(lì)下，從5I5能級(jí)躍遷至5G5能級(jí)后，這個(gè)能級(jí)上的部分離子輻射躍遷到基態(tài)產(chǎn)生425nm的紫色上轉(zhuǎn)換發(fā)光，剩余的離子經(jīng)過(guò)一系列快速的無(wú)輻射躍遷至5F3，5F4和5S2能級(jí)，最后電子從5G5，5F3，5F4和5S2，輻射躍遷回基態(tài)，分別發(fā)出位于486nm，561nm和656nm

這段文字中離子和電子需要標(biāo)識(shí)清楚，主語(yǔ)不順暢。說(shuō)剩余離子和最后電子…似乎有歧義。結(jié)尾一句不清楚。
1. 主語(yǔ)為elctrons, ions為主
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. 主語(yǔ)以electron energy level為主
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.
