I want to know the answer to the following question:
White LEDs can be made by coating what?
All the background I'm provided with is that "White LEDs can also be made by coating near-ultraviolet (NUV) LEDs with a mixture of high-efficiency europium-based phosphors that emit red and blue, plus copper and aluminium-doped zinc sulfide (ZnS:". Is that enough to answer the question?
Answer: yes
