Farewell to Jerusalem – well almost

Surface Plasmon Photonics has come to an end. Four hundred and fifty physicists are returning home, apart from the ones who, like me, have decided to have a short break to see a little more of Israel.

The conference was very interesting with many unpublished results presented, too many to cover here. In my final news from the conference I wanted to jot down a brief summary of two very applied talks on nano-textures for colour.

Firstly, Anders Kristensen, from DTU  talked on the work of plast4future They are particularly looking at nano-imprinted plastics to create colour from nano-textured surfaces for the automotive and toy industry. One of the project sponsors is Lego – I love the idea that such a traditional toy might one day have a 21st century technology on its surface to create its vibrant colour

The second talk to highlight was by Hans Lochbihler of Louisenthal. They were looking at similar technology but to create authentication labels for bank notes as these nano-textured colours have great security features.

For both applications techniques need to be found where nano-textures can be produced reliably at low costs for 10s of 1000s of square meters. I can sort of see that this technology might make sense for a bank note or the automotive industry but I find it hard to believe, given the average price per unit, that Lego bricks will ever employ this technology.
