A suite of silver (Ag) nanocr
ystals have been s
ynthesized using a rapid water radiol
ysis approach via X-ra
y irradiation. Various shapes including spheroidal, prism, rod, and multifaceted nanoparticles can be produced b
y var
ying the initial concentration of pol
yvin
ylp
yrrolidone (PVP) relative to silver nitrate (AgNO
3). UV鈥搗isible spectroscop
y and transmission electron microscop
y (TEM) coupled with selected area electron diffraction (SAED) have been used to characterize these Ag products. At an optimized reagent ratio, a mixture of high-aspect-ratio rods (tunable to 50) and spheroidal particles result. Such a mixture is proven to have highl
y beneficial melting point and dispersive properties suited to inkjet printing of conductive Ag lines. The resistivit
y of the printed lines decreases to 77.7 渭惟 and 33.1 渭惟 after heating to 200 and 350 掳C.
