Vertex 70v hyperion 3000

Surface characteristics of MNI-PDT were determined using X-ray photoelectron spectroscopy (XPS) by means of the K-alpha instrument (Thermo-Fisher, Waltham, MA, USA). The morphological properties of MNI-PDT were analyzed by Field emission scanning electron microscopy (FESEM) using the MIRA II KMH-TESCAN instrument. Energy-dispersive X-ray spectroscopy (EDS, X-act6, OXFORD) analysis was performed to determine elemental composition. The phase analysis to understand the level pureness of the sample was considered by XRD with Bragg’s diffraction 2θ (10 to 50°) with a 2°/minute scan rate by X-ray diffraction (Rigaku-D/MAX2500V/PC, Cedar Park, TX, USA). The absorption parameters were measured with the aid of a UV-VIS spectrophotometer (JASCO V-770, Oklahoma City, OK, USA). The photoluminescence characteristics were determined by a Cary Eclipse fluorometer (Varian, Palo Alto, CA, USA). Functional groups present in composite were studied by Fourier transmission Infrared spectroscopy (FTIR) by Bruker Optik GmbH, Ettlingen, Germany (FTIR, Vertex-70V/Hyperion 3000).

The DC of the resins was determined using Fourier transform infrared (FT-IR) spectroscopy (Bruker Optik Gm bH (Vertex-70V/Hyperion 3000)) in the total reduced reflectance mode. Specimens with standard dimensions (diameter = 15 mm; thickness = 1 mm; n = 5 per resin) were prepared from each resin. The specimens were analyzed in the range of 3500–500 cm⁻¹ at a speed of 4 cm⁻¹ using an FT-IR spectrometer in the attenuated total reflection (ATR) mode. A total of 32 scans were performed [33 (link),34 (link),35 (link)].
