Abstract

Cadmium-free thick-shelled InP/ZnSeS/ZnS quantum dot (QD) was synthesized using the heating-up approach. This quantum dots was used in inverted quantum dots light emitting diode (QLED) devices. The brightness of the inverted QLED device can reach a brightness of over 10 000 cd m , low turn-on voltage (2.2 V), and high power efficiency (4.32 lm W ).

摘要

采用升温法合成了无镉厚壳 InP/ZnSeS/ZnS 量子点 (QD)。该量子点应用于倒装量子点发光二极管 (QLED) 器件中。倒装 QLED 器件的亮度可达 10000 cd/m 以上，开启电压低 (2.2 V)，功率效率高 (4.32 lm/W)。
