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...
