</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)n^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-\frac{(\gamma_{TS}+\gamma_{TT})}{2}{T}^2+G_{T}


Where　

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

  • a : The type of exciton solver mode 
 1: Time-dependent triplet solver 
 123: Time-dependent triplet and singlet solver (For TADF OLEDs model)
 3: Triplet Exciton Solver (For PhOLEDs model)
 6: Singlet and Triplet Exciton Solver (For TADF OLEDs model)
 4: Triplet Exciton Solver with exciton blocking boundary 
 7: Singlet-Triplet Exciton Solver (For TTF/TADF OLEDs)
 71: Time-dependent singlet-triplet exciton solver with pumping time (For TTF/TADF OLEDs)
 711: Time-dependent singlet-triplet exciton solver (For TTF/TADF's TrEL and TRPL spectrum)
  • b : Start time (For time-dependent solver)
  • c : dt (For time-dependent solver)
  • d : End time (For time-dependent solver)
  • e : savenum (For time-dependent solver)
  • D : diffusion coefficient. (cm^{2}s^{-1})
  • kr : radiatvie rate constant (s^{-1})
  • knr :non-radiative rate constant (s^{-1})
  • gamma : quenching coefficient. (cm^{2}s^{-1})
  • g : generation rate if you wanna let whole recombination rate change into exciton you should set g as 1.
