A highly efficient and reliable hybrid quantum dot (QD) light-emitting diode (LED) is demonstrated and analyzed. The CdTe colloidal QDs are embedded in the sodium chloride (NaCl) ionic crystal to prevent external wear. The GaN-based ultraviolet (UV) LED is used as the excitation source. The mixture of colloidal QD/NaCl composite and polymer can be filled inside the standard LED package and optically...
An extended infrared photoresponse is observed in a ZnO/InN/GaN heterojunction diode with InN grown by MOCVD. The external quantum efficiency is measured between 1200 and 1800 nm and can be as high as 3.55%.
A highly efficient LED is demonstrated by incorporating the colloidal quantum dots and sodium chloride. Further lifetest shows great stability up to 104 hours under 194 mW/cm2 of UV pump power.
The photoluminescence (PL) with CdTe quantum dots (QDs) -NaCl crystals, mixed with organic film on glass substrate, was measured. This organic film was made by Polydimethylsiloxane (PDMS). Under different overlapping manner, a better PL intensity can be found at multiple layers condition.
