Abstract

In order to study up-conversion luminescence characteristics of Er

/Yb

co-doped YNbO

powder materials

the spectrum property was calculated by using J-O theory in this paper. The spectrum intensity parameters were obtained by the fitting method based on the absorption peak's area of the absorption spectrum

and the theoretical oscillator intensity and the experimental oscillator intensity were figured out according to the spectrum intensity parameters

and the mean square deviation of them(

rms

) was 3.91610

-7

. The parameters such as the transition probability

transition branching ratio and energy level life

etc

. of Er

particles in YNbO

powder materials were calculated

and the stimulated emission cross section of Er

radiative transition from the energy level

11/2

3/2

and

9/2

to the ground state was also figured out. The experimental results show that YNbO

is one kind of superior up-conversion matrix materials.
