摘要

Abstract

Cooperative luminescence (CL) occurs in spectral regions in which single ions do not have energy levels. It was first observed more than 40 years ago

and all results reported so far are from a pair of ions. In this work

upconverted CL of three Yb

ions was observed in the ultraviolet (UV) region under near-infrared (NIR) excitation. The UV CL intensity showed a cubic dependence on the NIR pump power

whereas the luminescence lifetime was nearly one-third the luminescence lifetime of single Yb

ions. The triplet CL (TCL) has a clear spectral structure

in which most emission peaks are consistent with the self-convoluted spectra from single Yb

ions. Blue shifts were observed for certain peaks

indicating complex interactions among the excited Yb

ions. The probability of the TCL process

versus

the average distances among three Yb

ions was derived

via

the first- and second-order corrections to the wave functions of lanthanide ions

indicating that the formation of Yb

clusters containing closely spaced ions favors the occurrence of the multi-ion interaction processes. Furthermore

the cooperative sensitization of one Gd

ion by four excited Yb

ions (Yb

-tetramer) was demonstrated experimentally

which exhibited a novel upconversion mechanism—cluster sensitization. Our results are intrigui

ng for further exploring quantum transitions that simultaneously involve multiple ions.
