Nanoparticles get the white light

White light emitting organic nanoparticles can be made simply by encapsulating an orange-red emitting dye within a scaffold of blue light emitting nanoparticles, say scientists in Japan. The material could be suitable for applications in optoelectronics and bio-imaging, they claim.

Masayuki Takeuchi and colleagues at the National Institute for Materials Science, Tsukuba, made an oligofluorene derivative that self-assembled in solution to form stable colloidal nanoparticles. They tuned the nanoparticles’ bright blue fluorescence to white through fluorescence resonance energy transfer by encapsulating DCM, an orange-red emitting dye, within the nanoparticle assembly.

  1. A friend of mine who subscribes to chemistry world, JAAS and a number of other RSC journals sent me a copy of a related article vie email. I must say this is an area that has developed tremendously and there are claims from a number of organisations that they have developed methods to yield particle size and chemical info from characterizing nanoparticles. Will be interesting to see developments
    in related areas here. As always the RSC delivers.
