Lasing conjugated polymers

Generally, photooxidation has an even stronger negative effect on lasing and stimulated emission in conjugated polymers than it has on the EL-performance. It not only reduces the number of excited 5j states but additionally creates charged absorbing species that partly compensate the stimulated emission due to the neutral excited states. [Pg.171]

Excitation conditions and threshold vulues for lasing in different conjugated polymers. Different resonator structures are used to achieve real lasing. Note that it is in some cases difficult to compare the values due to the different laser pulse duration used in the experiments. indicates the wavelength for excitation, r(,u< is the pulse duration of the exciting laser pulse atu A the urea of the spot on the sample. [Pg.177]
