Background
Quantum Dot Composition
For the manufacturing of quantum dot LED (QLED) displays, the quantum dots will have been created prior to 3D printing. The quantum dots will be made of the semiconductor, cadmium selenide/zinc sulfide (CdSe/ZnS), which consists of CdSe core and a ZnS shell. The ZnS shell on the quantum dot acts as a protective barrier between the core, which is responsible for optical emission, and the surrounding material [1]. Four sizes of quantum dots corresponding to four colors of emitted light will be purchased from mkNano.
The CdSe/ZnS quantum dots will be 3D printed on a crystalline ZnO wafer which will act as the electron injection layer. ZnO was chosen for its favorable band gap energy and work function [2]. The ZnO wafer substrate will be purchased from Precision Micro-Optics.
3D Printing CdSe/ZnS Quantum Dots
Steps:
- Acquire CdSe/ZnS quantum dots in water solvent mkNano
- Assuming it is possible:
- 3D print the cathode layer to the desired size
- 3D print the electron injection layer on top of the cathode
- Electron injection layer: Crystalline ZnO wafer
- Package the 5 quantum dot colors onto a vehicle (much like an inkjet printer)
- Print the quantum dots into a display array
- Again, assuming it is possible:
- 3D print a hole injection layer onto the quantum dot layer
- Print the final transparent anode layer onto the hole injection layer
This is where you can describe what already exists, what is needed, etc. You may want to include inline references. [3]
