| 摘 要： | The luminescence of Er^3＋：YAlO3 in ultraviolet visible and infrared ranges under the 518 nm excitation of the multiples ^2H11/2 have been investigated. Ultraviolet （275 nm and 318 nm）, violet （405 nm and 413 nm） and blue （474 nm） upconversion and infrared downconversion luminescence has been observed. By means of measuring the fluorescence decay curves and using the theory of rate equations, the luminescence kinetics was studied in detail and the processes of energy transfer upconversion （ETU） and excitation state absorption （ESA） were proposed to explain the upconversion phenomena.

| Abstract: | The luminescence of Er$^{3+}$:YAlO$_{3}$ in ultraviolet, visible and
infrared ranges
under the 518\,nm excitation
of the multiples $^{2}$H$_{11 / 2}$ have been investigated. Ultraviolet
(275\,nm and 318\,nm), violet
(405\,nm and 413\,nm) and blue (474\,nm) upconversion and infrared
downconversion luminescence has been observed. By means of measuring
the
fluorescence decay curves and using the theory of rate equations, the luminescence
kinetics was studied in detail and the processes of energy transfer upconversion
(ETU) and excitation state absorption (ESA) were proposed to explain the
upconversion phenomena. |
