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:
<math>\frac{dn_{ex}^S}{dt}=D^S{\nabla}^2{n_{ex}^S(r)}-(k_{r}^S+k_{nr}^S+k_{e}^S\times n+k_{h}^S\times p){n_{ex}^S(r)-\gamma{n_{ex}(r)}^2+G</math>
Triplet Rate Equation:
<math>\frac{dn_{ex}}{dt}=D{\nabla}^2{n_{ex}(r)}-\frac{n_{ex}(r)}{\tau}-\gamma{n_{ex}(r)}^2+G</math>


Where　
* <math>D</math> is diffusion coefficient.
* <math>\tau</math> is relaxation time of exciton.
* <math>\gamma</math> is annihilation rate constant.
* <math>G</math> is exciton generation rate.
