Which diamonds are we going to use in the end?

Our project is inexorably drawing to a provisional close, as our funding is due to run out soon. And yet we still have so many cool ideas for new experiments, formats and exhibits.

But one question remains! Which diamonds are we actually going to use? (see [https://qoool-sensing.org/en/news/17-Diamond-en/))

The answer is: all of them and more. Depending on the demonstrator and kit, we have opted for the diamond that is best suited in terms of both price and performance.

The microdiamonds from Adámas Nanotechnologies (MDNV150umHi30mg) are used in The Lämp and the QOOOL DIY kit.

But you can also use them to create other cool things, such as diamond arrays.

Shown here is a 5 x 5 array of aligned microdiamonds, bonded between two glass plates measuring 9 x 10 mm².

The diamond particles, measuring 700–850 µm in size and supplied by Adámas Nanotechnologies (MDNV700850um50mg), are incorporated into the QOOOL Kit Fluoro, meaning that the fluorescence can be seen with the naked eye and without a magnifying glass.

For the QOOOL Kit Magneto, Element Six’s HPHT diamonds (MD111/06 treated) are fitted into our π-MK1 platform.

As you can see, this means that all diamonds have found their way into our QOOOL kits. The only exception is the expensive CVD diamond (DNVB14), which we do not include in our QOOOL kits for cost reasons.
