Here is one sample I created and photographed showing the natural appearance and color of the nanoparticle suspension in white light (a), the Tyndall Effect demonstrated using a 532 nm green laser (b), and band bending phenomenon (c), which arises from quantum confinement effects (due to plasmonic resonance). This particular batch illustrates a blue-shift in near-UV light suggesting the sample has a unique band structure similar to antidots, and not like typical GQDs which posses narrow red-shifting that gives rise to photoluminescence (fluorescence). This particular colloidal nanosuspension is also exhibiting an extremely low water evaporation rate which was not expected. Minute droplets resist evaporation in an ambient environment remaining totally stable for several days now at RT.
Graphene quantum dots and even graphene antidot lattice arrays can be used for making photovoltaics such as LEDs and solar cells, filters and waveguides for optics, biological markers, novel catalysts for hydrogen generation, and even spintronic-based devices for quantum computers.
On a personal note, I have been making my own nanomaterials for little over a year now, all entirely from my private home lab. That's what happens when you decide to learn everything you can about chemistry, all the while performing more hands-on experiments to go even further. I recently enrolled at a 2-year college, and beginning to work towards my first real degree in the field - and am running towards that goal with every fiber in my being. It goes to show, anyone can do something it if want it bad enough - despite having limited funds or formal education. So, do not think it is too hard to understand or to do, unless you try, as you will be surprised how easy it just may be to reach your dreams when you have true desire and passion to see it through.
