| Abstract: | This paper studied the direct upconversion sensitization luminescence of Tm(0.1)Yb(10.9): oxyfluoride glass pumped by 966 nm diode laser. We found that there are strong 474 nm three-photon upconversion fluorescence of 1G4-->3H6 transition. As well as there are weak 362, 452 and 650 nm three-photon upconversion fluorescence of 1D2-->3H6, 1D2-->3F4, 1G4-->3F4 and 681 nm two-photon upconversion fluorescence of 3F3-->3H6 transitions respectively. Their upconversion mechanism has been analyzed and discussed simply. |
| Keywords: | Upconversion sensitization Tm and Yb codoped oxyfluoride glass |
