Fp 8300 spectro uorometer

All metal salts, chemicals, reagents and solvents of analytical grade were purchased from commercial sources and used without further puri cation. 4-tert-Butyl aniline and chloroacetyl chloride were obtained from Sigma Aldrich. Fluorescence active TLC plates (F-2009) were obtained from Merck. Fluorescence spectra were recorded on a Jasco FP-8300 spectro uorometer (Tokyo, Japan) with EHCS-813. Absorption spectra were recorded using a Jasco V-750 UV-Vis recording spectrophotometer (Tokyo, Japan) with EHCS-750 in the range of 200-800 nm. 1 H NMR, 13 C NMR, and 13 C DEPT spectra were obtained on a Bruker AV-(III) -400 MHz spectrometer using a BBFO probe. Mass spectra were recorded on a Micromass Q-TOF micro mass spectrometer with a capillary voltage of 3000 V and a source temperature of 120°C.

The structural properties of the prepared materials were recorded by X-ray diffractometer (Rigaku SmartLab SE) in the 2θ range of 20 0 -80 0 using Cu as a target (Cu K α =1.5406 Å) at 45 kV and 40 mA. The morphology of bare ZnO and Ag (concentration = 1, 3, 5 mol%) doped ZnO were observed by scanning electron microscope (SEM -ZEISS EVO18) and highresolution transmission electron microscopy (HRTEM, TEM -Thermo sher: Talos F200S G2). FTIR spectra were recorded on a ThermoFisher Scienti c iS50 spectrometer. The Raman spectra of prepared nanomaterials were analyzed by Raman spectrometer (NOST: HEDA-URSM4/5/7). The charge transport properties of Ag/ZnO nanocomposites were studied using Novocontrol Alpha-A impedance analyzer. The data of UV-visible spectra were analyzed through a UV-Vis NIR spectrophotometer (JASCO, V-670). The spectra of photoluminescence (PL) were provided by JASCO FP-8300 spectro uorometer.
