About this Physics and Astronomy article
Dynamics of visible-to-ultraviolet upconversion in YAlO3: 1% Er3+ by Huailiang Xu; Zhankui Jiang is a Physics and Astronomy article available to read on EtoBox.
The dynamics of visible-to-ultraviolet upconversion in YAlO 3 : 1% Er 3þ crystal has been investigated using the timeresolved laser spectroscopy when the sample was excited into the 4 S 3=2 multiplets. It is found that the upconverted luminescence is produced by energy-transfer upconversion or by excited-state absorption depending on the excitation wavelength. The dependence of upconverted luminescence on pump power is presented, and the relative intensities of upconverted luminescence were accounted for by Judd-Ofelt theory.
It is typically read by researchers, students, and practitioners in Physics and Astronomy.
