Experimental design could be the way to accomplish different goals, including
the design of structures with desired characteristics. In the present work, Zn(1-
x)Eu(x)O nanostructured arrays with different aspect ratio were synthesized using
a statistic factorial design 2 3 . The growth of textured surfaces by means of ALD
was performed on silicon substrates (100). The working conditions of the
textured film were made through the decomposition of diethylzinc (DEZn) at
190Ëš C and 3.29 x 10 -4 atm. Subsequently, the growth of nanostructures was
performed carrying out one factorial design considering a the solvothermal
microwave-assisted method (MASM). The experimental levels for every
considered factor were Eu 3+ concentrations of 0.02 and 0.06 (atomic %),
temperature of 80Ëš and 120Ëš C and time of 30 and 50 min. The reagents
used for solvothermal synthesis were Zn(NO3)26H2O and
hexamethylenetetramine (HMTA) as promoters. The Europium doped ZnO
nanostructures (ZnO-NS) were produced using Eu(NO3)35H2O as doping agent.
Each synthesis products were characterized through X-ray diffraction (XRD),
scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy
(XPS). Thus, it is demonstrated that is possible to produce nanorods with specific
size or shape as a result of every condition proposed in the experimental design.
