Application

The Green light-emitting spiro-copolymer is designed to deliver high efficiency and long-lasting performance in lighting applications. This innovative polymer generates a saturated green color while operating at a low voltage, making it both energy efficient and effective. In standard device configurations, it achieves a maximum efficiency of 11 Cd/A and a peak power efficiency of 12 lm/W. The external quantum efficiency stands at 4.1%, providing bright and vivid color reproduction with CIE1931 coordinates of (0.33, 0.59) at 100 cd/m². The device operates reliably at a turn-on voltage of 2.5 V, and maintains stability with a voltage of 3.6 V at 100 cd/m² and 6.0 V at 1000 cd/m². Its durability is underscored by a direct current (DC) lifetime of over 10,000 hours at 100 cd/m² and an alternating current (AC) lifetime exceeding 5,000 hours at 200 cd/m² when tested at room temperature, highlighting its potential for improved longevity and consistent performance.
