Factors that influence the spectral linewidth of an LED

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...
 

Thread 'Direction of the magnetic field of an oscillating charge'

Hello everyone, I’m considering a point charge q that oscillates harmonically about the origin along the z-axis, e.g. $$z_{q}(t)= A\sin(wt)$$ In a strongly simplified / quasi-instantaneous approximation I ignore retardation and take the electric field at the position ##r=(x,y,z)## simply to be the “Coulomb field at the charge’s instantaneous position”: $$E(r,t)=\frac{q}{4\pi\varepsilon_{0}}\frac{r-r_{q}(t)}{||r-r_{q}(t)||^{3}}$$ with $$r_{q}(t)=(0,0,z_{q}(t))$$ (I’m aware this isn’t...

Thread 'Initial conditions for orbits around a wormhole'

Hi, I had an exam and I completely messed up a problem. Especially one part which was necessary for the rest of the problem. Basically, I have a wormhole metric: $$(ds)^2 = -(dt)^2 + (dr)^2 + (r^2 + b^2)( (d\theta)^2 + sin^2 \theta (d\phi)^2 )$$ Where ##b=1## with an orbit only in the equatorial plane. We also know from the question that the orbit must satisfy this relationship: $$\varepsilon = \frac{1}{2} (\frac{dr}{d\tau})^2 + V_{eff}(r)$$ Ultimately, I was tasked to find the initial...
