a) Illustration of the omnidirectional wavelength-tunable color device featuring a mechanochromic chiral liquid crystal elastomer (CLCE) and an electrically deformable dielectric elastomer actuator ...
Tunable red to green emissions in upconversion nanoparticles allow precise identification of single particles, enabling accurate, long-term multicolor tracking in complex live cell environments.
A new technique?the result of an international collaboration of scientists from Lehigh University, West Chester University, Osaka University and the University of Amsterdam?could pave the way for ...
Light sources have historically been purchased with a specific color temperature — think “soft white” versus “cool white” fluorescent tube lighting. However, the industry-wide shift to LED lighting ...
New research demonstrates the possibility of tuning the color of a GaN LED by changing the time sequence at which the operation current is provided to the device. A new technique -- the result of an ...
