On the other hand, InAs, a material with a very low effective mass, significantly prolongs the carrier lifetime, enhancing the population inversion and increasing the dipole matrix element of the transition.
Two bicarbazole type host materials, 9- dibenzo [b,d]thiophen-4-yl)-9- dibenzo9H,9′H-3,3ʹ-bicarbazole (DBTBCz) and 9,9ʹ-bis(dibenzo [b,d]thiophen-4-yl -9ʹ-phenyl-9H,9′H-3,3ʹ-bicarbazole,d]thiophen-4-yl -9ʹ-phenyl-9H,9′H-3,3ʹ-bicarbazolels for blue phosphorescent organic light-emitting diodes (PhOLEDs).
In terms of oxygen sensing, the long lifetime enhances the chance of pyrene molecules in excited states to collide with oxygen molecules and renders oxygen-sensitive fluorescence.
The defect trapping can increase the carrier lifetime (enhancing QE); however, the response and recovery times also increase.
As a result, the average PL lifetime was enhanced by almost one order of magnitude from 39.4 to 376.9 ns with addition of 2D PVSK.
However, clustering algorithms require careful planning and design so that balanced and uniformly distributed clusters are created in a way that the network lifetime is enhanced.
Furthermore, experimental trends demonstrate that toluene conversion is highest at low water concentrations, however, mineralization and catalyst lifetime are enhanced by the presence of water.
The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced, and bandwidth reserved for each node maximized.
The network lifetime is enhanced by decreasing the number of transmitted packets per node.
In order to extend lifetime and enhance energy production of wind turbines in complex terrain it is important to learn about their wake characteristics.
Hard coating materials were widely applied on top surface of the molding dies to prolong lifetime and enhance the mechanical properties for glass molding mass production.
