Super-high color rendering properties of color temperature tunable white LEDs based on high quality InP/ZnS quantum dots via myristic acid passivation and Ag doping
چکیده انگلیسی
We reported two types of tunable white LEDs (WLEDs) based on high quality the single emissive InP/ZnS quantum dots (QDs) and the dual emissive Ag:InP/ZnS QDs via myristic acid (MA) passivation and Ag doping. The WLEDs with three color InP/ZnS QDs could realize color rendering indices (CRIs) of 97-98, color quality scales (CQSs) of 94-98, and limited luminous efficacies (LLEs) of 238-246 lm/W at correlated color temperatures (CCTs) of 2700 K to 6500 K, and the WLEDs with dual emissive Ag:InP/ZnS and red emissive InP/ZnS QDs could realize CRIs of 90-93, CQSs of 90-93, and LLEs of 223-242 lm/W at CCTs of 2700 K to 4000 K. Finally, their luminous efficacies were estimated.
