Verification of the luminous characteristics of the chip and phosphor in white LEDs.
White LEDs have a long lifespan and are energy-efficient, leading to a rapid increase in demand in recent years, particularly for lighting applications. White LEDs emit light through a blue semiconductor chip, which then excites surrounding phosphors (mainly yellow) to produce white light. Therefore, in investigating the improvement of luminous characteristics and the causes of degradation, it is necessary to confirm the luminous characteristics of both the semiconductor chip and the phosphor. A micro photoluminescence (PL) device can confirm the luminous characteristics by targeting small areas.
