Diamond, created by an infinite extension of sp3 carbon-carbon bonds, is the natural hardest material exhibiting high strength, corrosion resistance, high thermal conductivity, and optical ...

USING the 2536.5 radiation of the mercury arc as the exciter and a Hilger Intermediate quartz spectrograph, the faint second-order Raman spectrum of diamond was first successfully recorded by me 1.

In the course of an examination of the infra-red and ultra-violet regions of the spectrum of a large number of diamonds, we have come across one which, unlike the others, is transparent both at about ...

Engineers show nanoscale diamond's optical applications through a new class of Raman laser. This finding opens up new possibilities for broadband data communications. Diamonds are renowned for their ...

The Raman spectra of elemental carbon materials are sensitive to polymorphy. It is possible to band-fit the spectra of amorphous and diamond-like carbons for hard carbon films to decouple the ...
