oai:112.137.131.14:VNU_123-563432017-09-30T15:49:29Z Energy transfer studies of Dy3+ ions doped K2GdF5 crystal Vu, Phi Tuyen Phan, Van Do N.M., Khaidukov Nguyen, Trong Thanh K2GdF5 single crystal Inokuti – Hirayama model p. 112-116 Dy3+ -doped K2GdF5 single crystals were synthesized under hydrothermal condition. The UV excitation spectra and lifetimes of K2GdF5:Dy3+ were measured at room temperature. The excitation spectra have shown charge transfer state (CTS) of Dy3+ and energy transfer from Gd3+ to Dy3+ ions in K2GdF5:Dy3+ crystal. The decay curve of the K2GdF5 sample doped with 5.0 mol % Dy3+ ions is a non – exponential curve and is well fitted to the Inokuti – Hirayama model for S = 6. The energy transfer parameters (Q, CDA) and the critical distance (R0) are calculated. 2017-08-10T07:39:26Z 2017-08-10T07:39:26Z 2012 Article 2588-1124 http://repository.vnu.edu.vn/handle/VNU_123/56343 en Vol. 28;No. 2 (2012) application/pdf H. : ĐHQGHN |
