Physicochemical Impacts of Formation and Assembly of quantum dots Flowery Island of the (Sr-Cr-O) Semiconductor

In this paper, we fabricate a reactive self-assembled nanostructure of strontium chromium oxygen system (Sr
Cr-O). The ternary oxide SrCrO4 has been prepared as a QDs decorated superlattice. Course of formation as well
as the obtained composition was analyzed by a combination of Thermogravimetry (TGA), X-ray diffraction
(XRD), UV-vis diffuse reflectance spectra (DRS), scanning electron microscopy in association with EDX and
high resolution transmission electron microscopy (TEM). The obtained nanostructure was determined to be
composed of SrCrO4 as the major phase and SrCrO3/ SrO1.95 as the minor phases. Excitonic absorption signatures
in optical spectroscopy confirmed that quantum confinement is preserved. The methodology involves a modified
co-precipitation method. Moreover, excellent UV-visible-light photocatalytic performance was improved toward
Methylene blue dye.
