摘要：

We observed a blue-shift and narrowing of emission band of carbocyanine dye (BIC) J-aggregate in solution at high excitation intensity. This is explained by formation of a two-exciton state and efficient emission from the two-exciton to one-exciton state. The lifetime of the two-exciton state of BIC J-aggregate in solution is 30 ps at room temperature.
