</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}^{S,T}+k_{nr}^{S,T})S/T, [{S_1/T}_{1}\rightarrow {S_0/T}_{0}]

3. Singlet-Polaron Quenching: (k_{e}^Sn+k_{h}^Sp)S, [S_1+n/p\rightarrow S_0+n/p^{*}]

4. Triplet-Polaron Quenching: (k_{e}^Tn+k_{h}^Tp)T, [T_1+n/p\rightarrow S_0+n/p^{*}]

5. Triplet-Singlet Quenching: k_{TS}TS, [S_1+T_1\rightarrow S_0+T_1]

6. Triplet-Triplet Annihilation: \gamma_{TS}T^2+\frac{\gamma_{TT}}{2}{T}^2, [T_1+T_1\rightarrow S_0+T_1]\&[T_1+T_1\rightarrow S_1+S_0]

7. Triplet-Triplet Fusion: \alpha\frac{\gamma_{TS}}{2}{T}^2, [T_1+T_1\rightarrow S_1+S_0]

Where　

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