</math>Function for calculate the exciton distribution. We usually use this equation for organic material. Behavior of exciton will follow this equation. You can see the detail in Subroutine_exciton1D.

Singlet Rate Equation: \frac{S}{dt}=D^S{\nabla}^2{S}-(k_{r}^S+k_{nr}^S+k_{e}^Sn+k_{h}^Sp+k_{TS}T)S+\alpha\frac{\gamma_{TS}}{2}{T}^2+G_{S}

Triplet Rate Equation: \frac{T}{dt}=D^S{\nabla}^2{T}-(k_{r}^T+k_{nr}^T+k_{e}^Tn+k_{h}^Tp)T-\gamma_{TS}T^2-\frac{\gamma_{TT}}{2}{T}^2+G_{T}

Physical Mechanics
1. Exciton Diffusion: D^S{\nabla}^2{n_{ex}}

2. Exciton Quenching: (k_{r}+k_{nr})n_{ex}

3. Singlet-Polaron Quenching: (k_{e}^Sn+k_{h}^Sp)S

4. Triplet-Polaron Quenching: (k_{e}^Tn+k_{h}^Tp)T

5. Triplet-Singlet Quenching: k_{TS}TS

6. Triplet-Triplet Annihilation: \gamma_{TS}T^2+\frac{\gamma_{TT}}{2}{T}^2

Where 

  • D is diffusion coefficient.
  • \tau is relaxation time of exciton.
  • \gamma is annihilation rate constant.
  • G is exciton generation rate.
