Color Centers and Radiation-Induced Defects in ${Al}_{2}$ $O_{3}$

The peak energy

E_{0}

and full width

U

, in ev, of the color centers in

{Al}_{2}

O_{3}

before irradiation are:

E_{0} = 5.45

U = 0.6

;

E_{0} = 4.84

U = 0.54

; with an indication of a band at

E_{0} > 6.2

U > 0.4

. Irradiation of 3×

10^{4}

r produces saturation of the gamma-ray-induced bands which occur at

E_{0} = 5.45

U = 1.25

;

E_{0} = 3.08

U = 1.50

; and probably an additional band at

E_{0} = 4.28

U = 0.70

. Reactor irradiation produces bands at

E_{0} = 6.02

U = 0.60

;

E_{0} = 5.35

;

U = 0.40

;

E_{0} = 4.85

U = 0.54

;

E_{0} = 4.21

U = 0.80

;

E_{0} = 3.74

U = 0.88

;

E_{0} = 2.64

U = 0.64

; and

E_{0} = 2.00

U = 0.44
