Temporal evolution of the intensity of light scattered by evaporating microdroplets of SiO2 and polystyrene nanoparticle suspensions in DMSO and diethylene glycol, respectively.

The dataset comprises the results of measuring the temporal evolution of light intensity scattered by evaporating microdroplets of a SiO2 nanoparticle suspension with a diameter of 450 nm in DMSO, (SiO2 concentration was ~2 wt%) and a polystyrene nanoparticle(PSn) suspension with a diameter of 200 nm (3200A, Thermo Scientific) in diethylene glycol (DEG). These microdroplets were levitated in a quadrupole trap and illuminated by counter-propagating laser beams: a red (658 nm) vertically polarized (V) beam and a green (532 nm) horizontally polarized (H) beam, both with respect to the scattering plane. A comprehensive description of the experimental geometry is available in (M. Kolwas et al., Phys. Chem. Chem. Phys., 2015, 17, 6881--6888). The SiO2_450_DMSO_*.csv file includes the following data: Column 1: Time Column 2: Intensity of scattered light integrated over the field of view, with the laser and detection channel both vertically polarized (V) Column 3: Intensity of scattered light integrated over the field of view, with the laser vertically polarized (V) and the detection channel horizontally polarized (H) in cross-polarization Column 4: Intensity of scattered light integrated over the field of view, with the laser and detection channel both horizontally polarized (H) Column 5: Intensity of scattered light integrated over the field of view, with the laser horizontally polarized (H) and the detection channel vertically polarized (V) in cross-polarization Column 6: DC voltage applied to the upper and lower electrodes of the electrodynamic balance required to counteract the gravitational force Column 7: Operating frequency of the trapping AC electric field Column 8: Time evolution of the radius of the evaporating droplet obtained using the library method described in (D. Jakubczyk et al., JQSRT 126 (2013) 99–104). The SiO2_450_DMSO_*.avi files serve as examples of experimental measurements. The Ps_200_in_DEG_*.csv file includes the following data: Column 1: Time Column 2: Intensity of scattered light integrated over the field of view, with the laser and detection channel both vertically polarized (V) Column 3: Intensity of scattered light integrated over the field of view, with the laser and detection channel both horizontally polarized (H) Column 4: DC voltage applied to the upper and lower electrodes of the electrodynamic balance required to counteract the gravitational force Column 5: Operating frequency of the trapping AC electric field Column 6: Time evolution of the radius of the evaporating droplet obtained using the library method. The structure of the Ps_200_in_DEG_v3_Iv.csv and Ps_200_in_DEG_v3_Ih.csv files is as follows: the first column contains the observation angles, and the following columns contain the values of light intensity scattered by the droplet at corresponding angles. Each column corresponds to a specific moment in time. The time step between columns is equal to 0.029 seconds.
