The sizes of Psi in all solvents are almost the same, but distribution of Psi particles in the solvents quite different.
As seen in present results, intensities of Psi particles in solvents possibility depend on the nature of solvents and the cross-section area of etching.
Most of the Psi particles are uniformly dispersive and have sizes around more or less 5-8 nm quantifying of silicon wafer piece in etching process which leads to improve PL intensity and also is depending on the etched cross-section area of surface.
