Does anyone have an easy method to measure silicon nanocrystals content in a mixture?

Usually, I mix silicon nanocrystals with polymeric compounds to create a nanocomposite for the purpose of studying changes in the photophysicsl properties. The problem is that I am still having...

What is the main differences between the single photon excitation and multi photon excitation?

I am working to detect the lifetime decay for silicon nanocrystal, so I read about the topic for more understanding. Could you pick molicules as an example?. What will happen when a molecule is...

How can I determine the surface coverage for a functionalized silicon nanocrystal using TGA (Thermal Gravimetric Analysis )?

We are working on improving the structure and optical properties of silicon nanocrystals. So, we create passivated silicon nanocrystals using non-thermal plasma technique and then functionalize...

Is there a clear relation between the quantum yield (QY) and the peak-absorption intensity (Ib) for SiNCs?

Here, I am talking about silicon nanocrystals. As we know that the QY =(# of emitted photons / # of absorbed photons) *100 = #%. The number of the absorbed photons can be extracted from the area...
