Photoluminescence and excited state structure of Bi3+-related centers in Lu2SiO5:Bi single crystalline films
Result description
Single crystalline films of Lu2SiO5:Bi,prepared by the liquid phase epitaxy method from the melt-solution based on Bi2O3 flux, are studied at 4.2?350 K by the time-resolved spectroscopy methods under excitation in the 2.4?6.2 eV energy range. An intensedominant ultraviolet luminescence of Lu2SiO5:Bi is shown to arise from the radiative decay of the metastable and radiative minima of the triplet relaxed excited state(RES)of Bi3+ centers which are related to the 3P0 and 3P1 levels of a free Bi3+ ion,respectively. Characteristic parameters of the triplet RES,in particular the energy separation between the excited states and the rates of the radiative and non-radiative transitions from these states, are determined.
