Effect of Glass Matrix on Luminescent Properties of Tb3+ Doped Luminescence Glass
silicate and phosphate glasses and glass matrixes were prepared by high temperature melting technology. According to the UV-Vis transmission spectra
the experiment oscillator strengths of Tb
3+
from
7
F
6
to
5
D
3
and
5
D
4
were calculated
and the luminescent properties of Tb
3+
in different glass matrixes were explained. The results show that the 542 nm and 585 nm emissions of Tb
3+
doped in phosphate glass have split into two peaks because of the poor symmetry. In borate and silicate glasses
the particles in
5
D
3
energy level of Tb
3+
have been emptied and moved to
5
D
3
energy level because of the cross relaxation
so the emissions from
5
D
3
energy level (413
436 nm) are not obvious. In phosphate glass
5
D
3
energy level of Tb
3+
has much fewer particles and no cross relaxation
so the emission from
5
D
3
energy level is the strongest. The characteristic emission peaks of Tb
3+
from
5
D
4
energy level are 489
542
585 and 620 nm. In different glass matrixes
the order of their intensities from largest to smallest is borate
silicate and phosphate glass
which is consistent with the order of experiment oscillator strengths from
7
F
6
to
5
D
4
