Reaction between NO and O3 is a luminescence reaction and it forms NO2 and O2 with light. Why light it produced in the reaction. Is it because of at the end electrons NO2 going down from a higher state ?

If it yes , if we heat up NO2 will it make that glow again ?

In general yes. Chemiluminescence, as distinguished from photolyminescence occurs when a product or intermediate decays back down to the ground state.

 

Two excited state species or one ground state and one excited state species can also form an exciplex or excimer which can also give a chemiluminescent phenomenon.

 

There are even more rare third order processes as well.

 

I'm not familiar with the specific luminescence mechanism behind this reaction.
