Quantum D’s are alllll done
The QD thing is all handed in, just exams to go and education is dead.
I got a coupla last pix of fancy fluorescence (seen above) and also (and i can’t tell if this is exciting to any of you, but it certainly got me super hyped) managed to get some TEM (Transmission Electron Microscope) images of me dots.
The main thing that really gets me about these, is that those lil black and white crystals are literally smaller than the smallest virus (which is polio, with a radius of about 30 nm) the average crystal radius in my samples is ~2nm which is 0.00000002 meters, which is flippin tiny.
Which is important cus the reason they glow is that the wavefunction of the energy of the uv photon they absorb is constrained by the size of the crystal, therefore the size of the crystal directly impacts the energy of the emitted photon, so the different colours seen above is a result of the crystals being ever so slightly bigger or smaller than the other samples resulting in more or less constrained wavefunctions.
And then here is some close ups where you can see the crystal structure. I managed to make some tetrapods, (within the sample which is mostly smaller traditional spherical quantum dots) with a core and arms as can be seen.
So i hope you have enjoyed the mild insight into my sciency things that i’ve shown occasionally, cus they prolly ent coming back. <33333
