The Output Spectrum

After changing the width of the bands, record the output spectrum on a printed copy of the chart below:

The energy bands in LEDs are like energy lines in gases but much more concentrated. Electons can jump from any point of the conduction band to any point in the valence band. Based on this fact, the output spectrum should consist of the energies ranging from the smallest to the largest difference in energy between the two bands. Let us see if this is true.

Energy level of the bottom of conduction band:                 eV
Energy level of the top of the valence band:                       eV

Difference of the two: (smallest difference in energy)        eV

Energy level of the top of conduction band:                        eV
Energy level of the bottom of valence band:                       eV

Difference of the two: (largest difference in energy)          eV

Your output spectrum should range from the smallest difference to the largest difference in energy. Is that true?
