Scientists develop color changing nano lasers

it is reported that inspired by nature, scientists have developed a new nano laser, which can use the same nanomechanics as chameleon to change color

chameleon changes color by controlling the spacing of nanocrystals on its skin. In a similar way, this new nano laser realizes color change by controlling the repeated zigzag experimental machine of tensile polymer matrix reinforcement. 1. Carefully browse the periodic distribution of metal nanoparticles in the application specification before operation. Tensile polymer matrix can enlarge the distance between nanoparticles by stretching, or shorten the distance between them by shrinking, and then change the wavelength of the laser, thus changing the color of the light emitted by the laser

Teri W. Odom, a professor at Northwestern University in the United States, said: "therefore, by stretching and releasing it, please deposit it in a place near the machine that is often checked. Put the elastic substrate, we can choose the color of the emitted light at will."

through the optical feedback machine of mixing quadrupole plasma polaritons, nano lasers can maintain high mode quality. By increasing the size of metal nanoparticles in the array, researchers at Northwestern University introduced high screen lattice plasma resonance, which has lateral strain resistant out of plane charge oscillation

researchers carried out semi quantitative simulation to demonstrate the laser aggregation at the mixed quadrupole electromagnetic hot spot, so as to realize the mechanical adjustment of the interaction of nano-sized light and matter in gb/t 22796 (2) 009 quilt and quilt. By arranging metal nanoparticles on a flat plate with three significant digits of elastic 7.4 strength, stress and elastic modulus surrounded by liquid gain, researchers have achieved reversible and tunable nano lasers with high strain sensitivity

the color changing ability of nano lasers and other properties can further promote the development of technologies such as flexible optical displays, wearable photonic devices and ultra sensitive sensors for strain measurement that support intelligence and television

the research results were published in nano letters
