Abstract

/Yb

codoped and Tm

/Yb

codoped laurustinus shaped NaY(WO

)

microspheres were prepared

via

microwave assisted hydrothermal reaction. The XRD patterns indicated the resultant isbody-centered phase

and the SEM images showed the obtained samples are laurustinus shaped microspheres. In order to avoid the heating effect of high power infrared laser irradiation

the temperature sensing curve and sensitivity curve were obtained by using the down-conversion spectra at different temperatures under 380 nm excitation. Furthermore

a mixture with the weight ratio 1:10 of Er

/Yb

codoped NaY(WO

)

to Tm

/Yb

codoped NaY(WO

)

was prepared

and the upconversion emission spectra upon 980 nm excitation were measured. The laser irradiation induced thermal effect and the dependence of blue upconversion luminescence intensity on the irradiation time within 40 min were studied. It was found that the sample temperature was elevated at the initial time of laser irradiation

and then reached an equilibrium temperature. Additionally

it is also confirmed that the infrared laser irradiation affects the Tm

/Yb

codoped sample much more obviously than Er

/Yb

codoped one.
