Acknowledge your support! I've learned much from what you provided.

Greatly appreciate your information ! my materials is ZnO, modified by other elements, or doped. Intuitively, the exciton binding energy will change, nevertheless, I don't know whether it reduces or increases.

To measure the exciton binding energy, whether is it not enough to get absorption spectra ? for example, in an absorption spectra of UV-vis spectra under room temperature, there is no fine absorption values. Does the fine absorption values appear at low temperature, or other conditions ?

Thank you very much!

So what is binding energy equation for the Mott-Warnier excitons ? Would you please give further reference ? thanks

supplement to the problem: it's semiconductor powders, what dictate the exciton binding energy ? how could it be caculated ? how could it be tested ?

Hi, I want to test exciton binding energy of some particles, what should i do ?
