I can't remember...

[Deadmeat]

... what was the name of the process, when an electron changes its energy level and emmits photons. I did explain the process right, didi I? Even if I didn't, you get the idea...

 

I need information on this phenomenon, I really do.

 

Thanks to those who help!

As far as I know, there isn't a specific name for this. Its simply just absorption and emission of photons by an electron. When an electron goes from a lower energy level to higher one, a photon was absorbed, when it goes from a higher energy level to a lower one a photon is emitted.

Is 'transition' the word you seek? {E.g., Transition selection rules & probabilities, 'allowed' transitions, 'forbidden' transitions, etc.}. In dipole radiation, for instance, the theoretical differentiation between emission and absorption is simply a matter of +/- matrix elements.

[Deadmeat]

Hm, maybe. Yes, the process was when an electron changes its energy level.

 

May I get more information on this? Or is this it?

 

Anyways, thanks for the help!

It may be called an atom deactivation (opposite to excitation).

 

There are also processes called a radiative recombination.

[Deadmeat]

I don't think so.

 

Well, if photons are emmited, it's basically called glowing?

 

Well, I need info on the process itself and elements that have this, um, process.

Luminescence? Fluorescence?

[Deadmeat]

I'd go with Luminescence.

[ecoli]

I'd go with Luminescence.

 

You'd be wrong. Florescence is closer, but I think that's a more specific term.

[Deadmeat]

Explaine toe the dumbye?

[swansont]

Luminescence is a catch-all term for photons emitted from specific reactions, as opposed to thermal emissions from incandescence.

 

http://en.wikipedia.org/wiki/Luminescence

 

Fluorescence is a subset of luminescence, as is phosphorescence, which are two forms of de-excitation in which a photon is emitted

[Deadmeat]

Would the change of an energy level for an electron count as on of these "reactions?"

[swansont]

Yes, if a photon were emitted it would probably be considered fluorescence or phosphorescence.

[Deadmeat]

Ok, I've got the name. Now I need the info.

[swansont]

I gave you a wikipedia link. Did you look at it?

[Deadmeat]

Yep. But is there more to it?

[Genecks]

I think you're referring to quantum leaps within atomic structures: an electron changes an energy state and when it goes down an energy state, it releases light, which is a form of luminescence (I think). The input of energy, such as light, can make it leap to a more excited state. Leaping down from the excited state can cause it to release energy, such as light.

[swansont]

Yep. But is there more to it?

 

There are links to the phenomena in question. You'll have to be more specific if you still have questions.

Ok then. Thank you for your help.

 

 

 

As for Genecks, I agree with you. This might be quantum leaps, but I'm not entirley sure.
