Making UV light visible by exciting polarization-gate phototransistor to achieve energy transfer into GaN-based blue emission

We integrate polarization-gated UV phototransistor and blue InGaN/GaN mini-LED. The photon-generated electrons in the UV phototransistor make the mini-LED generate blue emission. This makes UV light “visible” to naked eyes.
