2D). This is possible by changing the material composition of the semiconductor which, once a current is applied, illuminates to the desired wavelength. Thus, LEDs are virtually able to emit any wavelength allowing for the fine-tuning of light spectrum. Light-emitting diodes are generally thought...
Body-conformable light-emitting devices have generated considerable interest because of their widespread potential applications in aerospace, medicine and electronics. These devices, which are flexible, stretchable and soft, can integrate seamlessly and inconspicuously with the human body for tasks such as...
Phased-array metasurfaces have been extensively used for wavefront shaping of coherent incident light. Due to the incoherent nature of spontaneous emission, the ability to similarly tailor photoluminescence remains largely unexplored. Recently, unidirect
Where Yijz denotes the independent observation for light type i in pair z at j weeks of age; μ is the overall mean; Li is the light effect; Aj is the age effect; Pz is the fixed effect of the pair which is the replication; βij is the interaction effect of light type and age;...
of maximum intensity. This LED has a pretty tight viewing angle. You can see that looking straight down at the LED is when it's at its brightest, because at 0 degrees the blue lines intersect with the outermost circle. To get the 50% viewing angle, the angle at which the light is ...
