WebMar 26, 2024 · Now because the energy of the photon is same as that of the energy of the transition energy, the electron in the ground state will move to the next higher energy level. This is known as absorption. But because the total energy of the atom is higher it would want to go to a lower energy level. This is known as spontaneous emission.
WebFor the photo-absorption curve, the absorption edge of the KNb 3 O 8 film is ∼350 nm, which corresponds to the bandgap of 3.54 eV, according to the equation: E gap = 1240/λ edge. However, the photo-absorption curve of KNb 3 O 8 film loaded with CQDs shows an obvious enhancement between 350 and 500 nm, which can be attributed to the ...

Our results suggest that BPQDs have great potential in applications as broadband optical limiters in the visible range or saturable absorbers in the near-infrared range for ultrafast laser pulses.
