摘要
The dynamics processes of 370-580 nm upconversion luminescence of HoP5O14 noncrystalline excited by DCM dye laser is reported in this paper. It is found that both mechanisms of energy transfer upconversion among ions and stepwise multiphoton absorption of single ion are involved in the upconversion luminescence, the upconversion dynamics would change greatly when the frequency of pumping laser has a little variation.
