What is the effect on capacitance of inter-digitated capacitor (IDC) with frequency?

Capacitance of IDC depends on the dielectric material used in IDC. I think, capacitance is decreased with increasing frequency because at high frequency dielectric don't hold the charge so charge...

In an Eu-doped lanthenide nano crystal, 5D0 to 7F1, the peak is less decreased compared to a 5D0 to 7F2 peak with delay time. Why is this?

I think the 5D0 to 7F1 transition peak is related to a magnetic moment which is changed due to material, less at time delay, while the 5D0 to 7F2 transition peak is related to an electric dipole...
