چکیده
pendence of time-resolved behaviors of another emission in ZnSe thin film at 470 nm. As the excitation power is increased, the faster component of duration less than 1 ps is also increased. This clearly indicates that the fast components are attributed to the stimulated emission from ZnSe under optical-pumping at 400 nm. The time decay and the delay relative to the pumping pulse of the emission maximum of the stimulated emission is changed with the excitation power. These interesting phenomena may be caused by the exciton-exciton scattering inside the thin-film znse. *Mailing address: 653 W. Hancock #B2, Detroit, Michigan 48201

متن کاملThin-film Encapsulation of Organic Light-Emitting Diodes Using Single and Multilayer Structures of MgF2, YF3 and ZnS
In this research, the lifetime of green organic light emitting diodes (OLEDs) is studied using four passivation layers. To encapsulate the OLEDs, MgF2, YF3, composed of alternating MgF2/ZnS and YF3/ZnS layers were grown by thermal vacuum deposition. Measurements show that the device lifetime is significantly improved by using YF3 and ZnS as passivation layers. However, diodes encapsulated by Mg...

Figure l(b) shows the wavelength-dependent time delay under different stretching voltages. The slope of the curve (i.e., the dispersion) at the operating laser wavelength can be changed by varying the PZT voltage. This grating enables compensation of dispersion accumulated for various distances as well as the dispersion accumulated in multiple subcarriers. Figures 2(a) and 2(b) show the effect ...

In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...

pulses is also measured with respect to the gate voltage and is shown in Fig. 3. The transmission decreases linearly proportional to the positive voltage. The best fit to this transmission versus voltage plot is obtained with a damping rate of 10 THz. Consequently, it gives a mobility of 110 cm~/v-sec. We have shown that the MOS inversion layer mobility can be measured without s o m e and drain...
