were stu-died. Based on up-conversion mechanism
energy matching and level
the effect of content of Ce
3+
and Al(PO

)

on the optical properties have been analyzed. The results show that the light changes from green to yellow then to red with the content of Yb
3+
/Er
3+
increasing and keeping the ratio of Yb
3+
/Er
3+
as 4 ∶ 1. And with the introduction of Ce
3+
into the glass
non-radiative relaxation takes place from the
4
I
11/2
to
4
I
13/2
level of Er
3+
which weakens the up-conversion of light to some extent. Phonon energy of energy transfer process of Er
3+
and Ce
3+
change with changing content of Al(PO)
3
and the degree of extinction also changes correspondingly. At the same time
through the mechanism of their up-conversion
we get the photon conversion process of red
green and blue light.
