We propose and demonstrate single-chip white-light-emitting diodes (WLEDs) integrated with semiconductor nanophosphors of colloidal quantum dots for high scotopic/photopic (S/P) ratio. These color conversion WLEDs achieve S/P ratios over 3.00, which exceeds the current limit of 2.50 in common lighting technologies, while sustaining sufficient levels of color rendering index.
我们提出并展示了一种集成半导体纳米荧光粉胶体量子点的单芯片白光发光二极管（WLED），用于实现高光效/高亮度（S/P）比值。这些颜色转换 WLED 实现了超过 3.00 的 S/P 比值，超过了当前普通照明技术 2.50 的限制，同时保持了足够的显色指数水平。
