AI Thread Summary
To activate Zinc Sulfide crystals for a glow-in-the-dark effect, incorporating copper impurities into the crystal structure is essential. The discussion highlights two methods for preparing these crystals: the combustion method, which the user has already tried, and the precipitation method, which is being considered. The user inquires about adding copper ions to the solution prior to precipitation to achieve the desired activation. One suggestion offered is to use electrolysis with a copper anode, which could theoretically introduce the necessary copper ions into the solution. Overall, the focus is on finding effective methods to create activated Zinc Sulfide crystals for short-term luminescence.

Hello. I am trying to activate crystals of Zinc Sulfide in order to get the crystal to glow in the dark. I do not need a long-term or powerful glow, I am merely investigating whether it is possible.

How can I prepare Zinc Sulfide crystals that have copper impurities as part of the crystal structure? See the Wikipedia article below for a description of why this is necessary for a glow. I have made Zinc sulfide through the combustion method, but I was considering instead trying the precipitation method. If I were to add Cu ions to the solution before precipitation, would this allow me to create the activated Zinc Sulfide Crystals?

This is an area of chemistry I know nothing about, so I really do appreciate any advice. Thanks!

I don't know much about the subject, but you could try an electrolysis using a copper anode. That would put some of the ions necessary into the solution. (Theoretically anyway) Good luck with it! (are you detecting alphas?? :P )
 
Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'
I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
