Fig.S1 XRD patterns of the CaTi0.9O3:Tm,Ni upconverter with
variable concentrations of Tm doping.
Fig.S2 XRD patterns of the CaTi0.9O3:Tm,Ni upconverter with
different alkali ions codoping of the amount equivalent to that of
the Tm ions.
Fig.S3 XRD patterns of the (Ca/Sr/Ba)Ti0.9O3:Tm,Ni upconverters
exhibiting the orthorhombic, cubic and tetragonal phases.
Fig.S4 XRD patterns of the Ca(Ti/Zr/Hf)O3:Tm,Ni samples
exhibiting the orthorhombic crystal phase.
Fig. S5 Comparison of the UC emission intensities (integrated
over 760-860 nm) for the CaTiO3, CaZrO3 and CaHfO3 samples
containing Tm only and Tm, Ni. Note that the UC emission
intensities of the three samples are normalized separately.
