Abstract
Recent years
Up-conversion(UC) luminescence exhibits potential application in temperature measurement based on FIR(fluorescence intensity ratio) technique
which has drawn considerable attention. Lanthanum oxyfluoride(LaOF) inherits the advantage of low lattice phonon energy
and exhibits superior thermal and chemical stability
showing efficient UC luminescence. Thus
limited attention has been paid to the temperature sensing characteristics of Er
3+
/Yb
3+
co-doped LaOF. In the present work
rhombohedral LaOF:Er
Yb phosphors are prepared using hydrothermal method. The structure and fluorescence properties are characterized by X-ray diffraction
SEM and fluorescence spectra. Hexagonal LaF
3
is prepared using hydrothermal method at 120℃. After annealing at 1 000℃
rhombohedral LaOF is obtained. The agglomerated particle crystallizes into one larger particle in the range of several micron following annealing. Excited by 980 nm
the characteristic emission from the Er
3+
ion is observed
including two green emission bands and one red emission

is confirmed because of two-photon process
resulting in upconversion emissions. Finally
the optical temperature sensing properties of R-LaOF:Yb
Er are investigated. The results suggest that R-LaOF:Er
Yb exhibits intense emission and high sensitivity. Its maximum relative sensitivity
