展示了一种高效的混合色转换发光器件，该器件由胶体量子点（NQD）和表面图案化GaN基LED组成（见图）。表面图案化LED中的激发经由非辐射能量转移有效地转移到NQD发射器。实现了NQD发射的两倍增强。
An efficient hybrid color-conversion light-emitting device consisting of colloidal nanocrystal quantum dots (NQDs) and a surface-patterned GaN-based LED is demonstrated (see figure). Excitation in a surface-patterned LED is efficiently transferred to NQD emitters via non-radiative energy transfer. A twofold enhancement of the NQD emission is achieved.
