← TechnologyWhich consequence results when rapid LED current spiking occurs?
A)Phosphor thermal quenching increases✓
B)Radiative recombination event increase
C)Built-in voltage overshoot decreases
D)Electron hole mobility degrades slowly
💡 Explanation
An increasing phosphor's thermal quenching can result from current spikes; increased power dissipation causes lattice vibrations resulting in non-radiative relaxation channels; therefore luminescence decreases rather than showing alternatives because thermal management isn't optimal.
