Optical methods and optical devices using the semi-continuous metal film nano-particles, and micro-cavities,

摘要

A medium containing (32) interconnected nanoparticles including a plurality of fractal, A (created and a corresponding method) optical sensing enhancing material comprising a (44) micro-cavity, the medium is placed close to the microcavity. It also provides, to be placed close to the microcavity medium is doped, (including agglomerated nanoparticles including a plurality of fractal medium) a light source medium is doped medium is doped with material sensing method and an optical sensor for detecting light reflected from the medium to excite, was doped. Also, (medium comprises a semicontinuous metal film clusters and their metal particles randomly distributed in the percolation threshold of approximately their) light sensing enhancing material include medium. Preferably, the medium further comprises a microcavity / microresonator. In addition, devices and methods to use the substance. [Selection] Figure 12
