Study of ZnS:Mn2+,Te2+ phosphor for improving the hue rendering indicator of WLEDs

This research combines a phosphor-in-glass (PiG) YAG:Ce3+ with red liquid-type quantum dot (LQD) to invent high-quality white light-emitting diodes (WLEDs). When the PiG LQD-built WLEDs reach 100 mA, they provide heated illumination offering an outstanding color rendering index (CRI) (Ra=93.9, R9=97.7, and R13=98.1). The luminescent efficiency (LE) correlating chromatic temperature, correspondingly, are 62 lm/W 3764 K. In comparison integrated solid-kind dot, it has great LE, remarkable CRI, lower top layer temperature because of self-aggregation impediment in outside flaws semiconductor dots (QDs) solid-condition, as well effective thermal dissipation. findings suggest that produced could be potential lighting applications.
