Bike has quit [Quit: Lost terminal]
<Noxz> yeah, I watched his video yesterday I think
<Noxz> there wasnt too much chemistry wise, more so procedure
<nmz787> I learned AgCl + 405nm laser -> metallic Ag by getting an electron from CuO... which eventually reverses after some time
<Noxz> I looked into some phosphorescent stuff which was usually dopped with Cu particles, so that does make some sense
<nmz787> this book has some recipes and such including BOMs for making your own CRT with phosphorescent stuff and a flat bottom flask
<Noxz> I was looking at the phorescents actually from his SEM build
<Noxz> to have an easy initial visual clue that e- were getting to a target point
<Noxz> I think the 'standard' glow powder is zinc sulfide + Cu particles
<Noxz> I bought a small amount from TAP plastics cuz they had it, and I was doing some halloween stuff ;)
<Noxz> made glow slime
<Noxz> the glow eventually settled to the bottom though
<Noxz> he actually used phosphorescence as the reciever/amp part of his SEM
<Noxz> I plan on using MgO on nichrome mesh, layered, as secondary electron cascading
<Noxz> MgO from Mg(OMe)2 that upon heating methanol is released
<Noxz> or something like that, I'd need to lookup again
<Noxz> but yeah, going more with electron amplification vs e- to photon to photodetector
<nmz787> mmm, cool
<nmz787> is that what the 'direct electron detectors' do (in the current-gen SEM/TEM market)?
<nmz787> halloween is a good excuse to play with phosphors! :)
<Noxz> they need to amplify it
<Noxz> yeah
<Noxz> Secondary Electron Emission
<Noxz> and I basically chose MgO because it is simple to make from Mg(OMe)2 (which is super simple to make)
<Noxz> heating Mg(OH)2 which it would become in air results back to MgO
<Noxz> and since I am thinking of a nichrome mesh, well, that is easy to heat
<Noxz> so, a relatively simple process to get it to MgO, imo
