Introduction 
Enormous progress in nanomaterial research has been achieved to 
prepare nano-level material having supportive properties such as 
improved electrical conductivity, toughness and ductility, and the 
higher hardness number. It is well known that the Nano-sized 
particle is restricted under the law of quantum theory and lies 
between below 100 nm and higher than the diameter of an atom 
[1,2]. In this recent year, researchers are focusing on synthesizing 
Erbium nanoparticles among many rare metal Nano-materials, 
because they find one of the rare earth metals which acts as a 
sensing component and amplifier in the biomedical field and 
optical devices respectively [3,4] and therefore the popularity of 
rare earth metal nanoparticles has increased. Since the property 
(electrical and optical, etc.,) of ETO-NP (or rare earth nano- sized 
metal particles) differs from the distribution of Erbium particles 
in micro dimensions. These unique properties support ETO-NPs 
(or rare earth nano-sized metal particles) to gain various 
applications such as Nano-sized particle coating in paints which 
act as corrosion to an environmental factor, optical probe 
Scanning thermometry [5] Nano thermometers [6] cancer-targeted 
or tumor NIR imaging, to cure cancer cell line against breast 
cancer, brain cancer and ovarian cancer, antibacterial assay [7-12] 
and drug delivery system [13], etc. Also, studies show that ETO-
NP can degrade Rhodamine Dye from the contaminated water 
containing Rhodamine Dye [14,15]. Further studies revealed that 
the incorporation of Erbium oxide doped nanoparticles on the 
glass or plastic resulted in an application of creating display 
monitors. Due to the large bandgap and dielectric constant (10-
14) values, erbium oxide is used as a gate logic device in 
semiconductors [16]. The most unique properties of rare earth 
nano-sized metal particles arise due to the transition of electrons 
within the 4f-shell which permits them to act as luminescent 
materials. To synthesize ETO-NPs (or rare earth nano-sized metal
