White LED with no Phosphorus ?

[fenixmad]

What would emit from the LED if the phosphorus was scraped off the die? would you get pure blue? or would you get UV?

You would get blue light.. Around 450nm or so of light..

You'd get a royal blue.

UV is not common in the white LED industry, but, still possible.

I believe that there are some LEDs that use a UV die but they aren't as efficient so they aren't as popular. Most LEDs us a blue die though.
