Visible and infrared emission from Er₂O₃ nanoparticles, and Ho⁺³, Tm⁺³, and Sm⁺³ doped in AlN for optical and biomedical applications

Description

Rare-earth ions holmium (Ho+3), Thulium (Tm+3), and Samarium (Sm+3) were investigated for
infrared emission and their possible biomedical applications by a photoluminescence (PL)
system. Holmium’s (Ho+3) emission peaks were the result of transitions
5
S2 →
5
I7,
and
5
S2 →
5
I5
respectively. Samarium’s (Sm+3) emission peaks were 936 nm and 1863 nm. Thulium’s (Tm+3)
emission peaks were the a result of transitions
3
H4 →
3
H6,
3
H5 →
3
H6 , and
3
F4 →
3
H6 respectively.
Erbium Oxide nanoparticles (Er2O3) mixed with water by a photoluminescence (PL) system.
Erbium Oxide’ (Er2O3) nanoparticle’s emission peaks were the a result of transitions
4
I15/2 →
4
S3/2
,
4
I15/2 →
4
I13/2 respectively. The process was also repeated in vacuum and it was found that
the green emission enhances tremendously when the nanoparticles are excited in vacuum. This
enhanced luminescence from the Erbium Oxide nanoparticles shows their potential importance
in the optical devices and Biomedical applications. / Department of Physics and Astronomy
