Ultra scan 400sp

Example 1

Analytical Methods:

X-ray diffraction (XRD) analyses were performed on a Bruker D8 Advance diffractometer system with an operating voltage of 40 kV and a current of 40 mA by using Cu Kα radiation (λ=1.5405 Å) and a graphite monochromator. The samples were investigated over the 28 range 10-80° at a scanning speed of 2 min⁻¹. Fourier transform infrared (FT-IR) spectra were collected on a Bruker FT-IR spectrometer by using the KBr pellet technique. Thermal gravimetric analysis (TGA) analyses were carried out using a thermogravimetric analyzer (Discovery, TA, USA). A 5.0 mg sample was placed in an aluminum pan and heated from 30 to 600° C. under N₂ at a heating rate of 10° C./min. The morphologies and sizes of the resulting products were determined with field emission scanning electron microscopy (TESCAN LYRA3, Czech Republic). TEM images were recorded by using a transmission electron microscope (JEOL, JEM 2011) operated at 200 kV with a 4 k×4 k CCD camera (Ultra Scan 400SP, Gatan). PL measurements were performed with a spectrofluorometer (Fluorolog FL3-iHR, HORIBA Jobin Yvon, France). The chemical compositions of the samples were determined with X-ray photoelectron spectroscopy (XPS) by using an X-ray photoelectron spectrometer (ESCALAB-250, Thermo-VG Scientific) with Al—Kα radiation (1486.6 eV).
