Can somebody help with steady state emission data of CdSe-QDs+MO2 (M=Ti or Zr) solutions?

I am doing some control experiments with CdSe QDs-MO2 (M=Ti or Zr) colloidal solutions. According to literature, I should see lesser quenching of emission with ZrO2 as compared to TiO2 as the band...

How can I measure the longer fluorescence lifetime component of quantum dots using TCSPC?

Hello, I am using a Becker and Hickl Tau130 TCSPC system to calculate fluorescence lifetimes of CdSe quantum dots. With me early measurements I have observed that QDs show multi-exponential decay...

Can anyone help with measuring IRF (instrument response function) for fluorescence lifetime experiment by TCSPC.

I have been using water to scatter light for measuring IRF of my TCSPC setup. I have also try to use paper. But when I was searching online, I saw that people generally use colloidal silica/ ludox...
