Δ. E = the emission energy. 3. Results . We presents the values of the parameters used and the results obtained with the dimensionless and physical 2015-11-20 Brus Equation The Brus equation [1] can be used to describe quantum dot emission energy (𝐸𝑄𝐷) as a function of the radius (𝑅) and its bulk material properties; band gap (𝐸𝑔) and effective masses of electrons and holes (𝑚𝑒∗,𝑚ℎ ∗). This is achieved by modelling the electron and hole Question: 3. The Brus Equation Can Be Used To Describe The Emission Energy Of Quantum Dot Semiconductor Nanocrystals (such As CdSe Nanocrystals) In Terms Of The Band Gap Energy Egap, Planck's Constant H, The Radius Of The Quantum Dot R, As Well As The Effective Mass Of The Excited Electron Me* And Of The Excited Hole Mh The Radius Of The Quantum Dot Affects The Quantum confinement effect in semiconductor quantum dots (QD's) of CdSe, ZnS and GaAs has been studied using the Brus Equation. It is found that the simple models obtained for the three different semiconductor nanocrystals exhibit the size dependence predicted by the particle-in-a-box model.
