Dataset for Blue Laser for Production of Carbon Dots

The PCL + CDs composites were studied using attenuated total reflectance coupled with Fourier transform infrared spectroscopy (ATR-FTIR) and were monitored using a JASCO Model 4600 spectrophotometer working in the (400–4000) cm−1 wavenumber range.

The luminescence of the produced CDs was observed using the Avantes AvaSpec-2048-USB2 optical spectrometer. The luminescence was monitored in the transmission mode in the region 200–800 nm. The exciting UV light source operating at 365 nm and at a fluence of about 100 mJ/cm2 illuminated the front of the cuvette containing the CD suspension at a 10 cm distance and at 0°, while the fiber connected to the spectrometer was located on the back of the cuvette at a 1 mm distance and at 180°.

The silicon cuts 1 cm × 1 cm in size were covered with drops of CD suspension and dried in air overnight. The formed films were studied by AFM. A dimension ICON AFM system (Bruker Corp., Bremen, Germany) operating in the ScanAsyst imaging mode in air has been employed. A commercial silicon Tip and SCANASYST, in air mode, with a spring constant of 0.4 N/m, supported 3 μm2 scanning. The identification of the CDs was carried out using AFM images recorded and processed using NanoScope Analysis 1.80 with 32-bit software.
