have attracted a great deal of attention for applications in memory devices
and as phosphor materials. The broad emission of Eu
2+
ions is host
sensitive. Depending on the host matrix, Eu
2+
ions could emit from the UV
to the red region of the electromagnetic spectrum.
It has been shown that Eu
3+
ions were spontaneously reduced in a sol-gel
matrix during densification.
