6. In your laboratory notebook, draw an energy diagram for your semiconductor sample. Onyour energy diagram, draw the transitions showing the absorption of the blue-violetphoton (4.5x10") and the fluorescence (emission) of the yellow photon (3.5x10"]).Make sure to adjust the energy diagram (1e. the single conduction band and the singlevalence band) on the scale and to adjust your arrows' length and direction so that they areconsistent with the photons described.

In semiconductor we know the conduction band contain null, and valence band is fully filled, and…
