Rare earth mineral shortage.
Let’s remind ourselves Light emitting diode definition. It’s a semiconductor which emits a
Particular wavelength when crossed by low electrical voltage current. Property semiconductor matter gives to Led a big light output and faster emission. Synthesis is not as efficient. We have then to avoid shortage. In a circular economy manner.
Searching for rare earth mineral shortage and how to keep them …
