Silver nano particles (Ag NPs) with narrow
size distribution were derived chemically by sol-gel
process and characterized by XRD, and highresolution
transmission electron microscopy (HRTEM) techniques
to confirm their formation, morphology, particle size
and distribution properties. The variation in size of as
prepared Ag NPs were monitored periodically every
month by HRTEM for the last six months to check the
stability of nanoparticles with time to assign the shelf life
of Bhartiya NideshakDravay (BND) and estimated the
overall expanded uncertainty in size of nanoparticles.
The traceability of the developed silver nanoparticles
will be derived from the NIST standard reference
materialor from other NMI which established facility for
assigning particle size. Such Ag NPs BNDs of different
particle sizes can be used for calibration of instruments
like TEM/HRTEM and particle size analyzersfor
research and find usagein many industrial applications
with global acceptance.
