P‐131: Thermally Stability study for Quantum Rod On‐chip Light‐Emitting Diodes under High Power Illumination

Abstract

Down‐conversion quantum dot on‐chip LED is favored by researchers in the new era due to its excellent optical performance. However, these materials show strong temperature dependence. To solve the thermal stability problem, in this work we studied red CdSe/CdS/ZnS core multi‐shell quantum rods (QRs). We found that these specially designed QRs provide a stable photoluminescence properties at relatively higher temperatures. The QRLEDs show 95% of the light intensity at 75 degrees, far exceeding the red‐light epitaxial grown LEDs available on the market. Thus, the quantum rods can be a potential candidate for the micro‐LEDs and LED products.
