A green LED (1) has a substrate (11), a GaN heavily n-doped bottom confining layer (12), an active region (13), an upper GaN confinement layer (14), and a semi-transparent ohmic contact layer (15). The active region (13) has less than or equal to three highly compressively ...
Herein, highly-efficient quantum dot light-emitting diode (QLED) with stacked blue and yellow quantum dot (QD) layers can be demonstrated to output white light. The buffer layer of ZnO nanoparticles (NPs) inserted between two QD layers can prevent them from mixing and penetrating. In order to...
A light emitting diode (LED) includes a p-n junction containing luminescent activator ions. The visible emission from the activator ions preferably complementing the band edge emission of the LED in order to produce an overall white emission from the LED. In a preferred embodiment, the LED has...

Thermal resolution (also referred to as temperature uncertainty) establishes the minimum discernible temperature change sensed by luminescent thermometers and is a key figure of merit to rank them. Much has been done to minimize its value via probe optim
Er clustering plays a major role in hindering sufficient optical gain in Er-doped Si materials. For porous Si, the long-standing failure to govern the clustering has been attributed to insufficient knowledge of the several, concomitant and complex processes occurring during the electrochemical Er-dopi...
