So I'm doing up a physics report but i got stuck on this question :(

Q: Explain the factors that influence the spectral linewidth of the emission spectrum.

i'm guessing that it has something to do with the types of elements used in doping the semiconductor? but i don't know how the theory part goes exactly.

please help D;
thanks in advance!

i've been googling extensively but i can't seem to find anything helpful... been flipping through notes but it doesn't mention spectral linewidth at all :-( sigh.

Really? When I Google spectral linewidth of an LED (directly from your thread title), I get lots of great hits. The first hit on the list would seem to be a good answer...
