Why is there a split in single particle resonance dip (in transmission spectra) when the periodicity of nanoantenna arrays is increased?

I have fabricated Ag nanoantenna arrays on glass. It consists of cylindrical nanoantennas at constant separation in symmetrical environment. I have observed a splitting of single particle...

Does anyone have idea about the change in spectra of CdSe/ZnS quantum dots on aggregation?

I am getting two dips in transmission spectra other than at absorption wavelength for CdSe/ZnS quantum dots. I am not sure about the reason but aggregation could be a reason behind it? Does...
