Excited-state reversible geminate recombination with two different lifetimes and quenching is investigated in two dimensions. From the exact Green function in the Laplace domain, analytic expressions of two-dimensional survival and binding probabilities are obtained at short and long times. We find that a new pattern of kinetic transition occurs in two dimensions. The long-time effective survival probabilities show a pattern of (ln t)(-1)-->constant-->e(t) depending on the rate constants while the effective binding probabilities show t(-1)(ln t)(-2)-->t(-1)-->e(t).
在二维空间中研究了具有两种不同寿命和猝灭的激发态可逆孪生复合。从拉普拉斯域中的精确格林函数，我们在短时间和长时间内获得了二维生存和结合概率的解析表达式。我们发现二维空间中出现了一种新的动力学转变模式。长时间有效的生存概率显示出一种取决于速率常数的模式（ln t）(-1)-->常数-->e(t)，而有效的结合概率则显示出 t(-1)(ln t)(-2)-->t(-1)-->e(t)。
