-doped Gd

phosphor is demonstrated from the curve of concentration quenching. By analyzing the temperature character of the phosphors

the activation energy of samples with 5% and 20% doping mole fractions is obtained and the experimental values are 0.27 and 0.29 eV

respectively. The temperature characters of samples with two different doping concentrations are analyzed by means of fluorescence intensity ratio from

and

3/2

15/2

radiative transitions

indicating good temperature sensor for the present materials.
