can you 'shine' candoluminescent materials coated on metals with induction?

I don't know that burning carbon would do it.  CO does burn with a pale blue flame.  Doubtful a powder or pressed composition would keep the REO around long enough to be significant.  It would just cool down the composition.  Much better to burn the metal directly, i.e. Al, Mg or Ti typically.

I wonder if burning Mg vapor excites MgO. Sure seems like it.  The vapor seems to burn orange (which may just be sodium present), but where it lights the oxide, brilliant white.

i don't think it would cool it down significantly. It would be a challenge not to destroy it IMO.
coppercone2:
another idea, can you like, heat it with EM and then pass gas at a lower pressure over it?

The idea being to minimize the amount of gas used. I don't understand the reaction. Do you need the stuff hot and the radicals will form or do you need the actual combustion reaction to be happening at the candoluminsent material matrix?

Typically I guess they coat the mesh with its oxide and heat it with a flame. As pointless as it is, can you use induction or microwaves to heat some kind of susceptible matrix to turn it into a light source?

Hi coppercone2

Not sure if this is of interest/relevant, but you can illuminate fluorescent tubes with RF. We used to point aircraft radars at the hanger ceiling florescent lighting as a quick check to see if the radar was working.

I thought nothing could convert heat into anything else. Some law of thermodynamics?

A heat difference between two reservoirs can be converted to more useful forms of energy (Sterling cycle, etc), sure, but not just heat in one place like you'd be claiming here.
