Dynamics of visible-to-ultraviolet upconversion in YAlO3: 1% Er3+
Research output: Contribution to journal › Article
The dynamics of visible-to-ultraviolet upconversion in YAlO3: 1% Er3+ crystal has been investigated using the time-resolved laser spectroscopy when the sample was excited into the S-4(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. (C) 2002 Elsevier Science B.V.
