Want to make phosphorescent ink? Dope it with some europium.

We live in a golden age of printing in which it’s possible to churn out tools, weapons, and even experimental artificial organs. Now, scientists at ITMO University in Saint Petersburg, Russia are engineering yet another specialized field of futuristic printing—luminescent holograms that can be produced by a normal inkjet model printer.
In a study published in the journal Nanoscale, researchers led by Alexandra Furasova introduced a new type of „nanoparticle ink“ made with zirconium dioxide crystals that are „doped“ with the phosphorescent element europium.
