White-light-emitting diodes using semiconductor nanocrystals
The degree of lumen degradation over test time is shown in Fig. 2, and the overall luminescence intensity weaken with test time, revealing degradation occurs in the duration of working condition. According to the lumen variation shown in Fig. 2, the degradation can be divided into three stages, namely enhancement … Visa mer In the enhancement stage, light conversion efficiency of QDs increases during the initial 6 h and followed by a rapid degradation subsequently. The increase in the light … Visa mer Figure 10 shows the variations of absorption and PL spectra of CdS/ZnS QDs with time. In the case of QDs at 18 and 220 h of working … Visa mer It is reported that the oxidation of QDs is mainly dominated by oxygen rather than H2O29, only oxygen is involved in our DFT based simulation. The structure for tracing the Minimum Energy Path (MEP) is designed by … Visa mer Webb13 nov. 2008 · White light-emitting diodes (WLEDs) were fabricated by combining blue InGaN chips with luminescent colloidal core/shell CdSe/CdS/ZnS quantum dots (QDs). … nail tech album
