Background:

Quantum-dot light-emitting diodes (QD-LEDs) show promise for advanced display technologies.
Current fabrication methods for inverted QD-LEDs often employ hazardous solvents for hole transport layers (HTLs), posing environmental and health risks.
Intermixing between HTL and quantum dot (QD) layers is a significant hurdle in achieving high-performance inverted QD-LEDs.

Purpose of the Study:

To establish a green solvent selection procedure for fabricating high-performance and environmentally safe QD-LEDs.
To identify optimal solvents that prevent interlayer mixing and maintain smooth interfaces in inverted QD-LEDs.
To replace hazardous solvents commonly used in HTL processing.

Main Methods:

Utilized Hansen solubility parameters and surface roughness analysis to screen potential solvents.
Employed the CHEM21 solvent selection guide to filter out environmentally hazardous options.
Evaluated 16 candidate solvents, ultimately selecting cyclopentanone (CPO) as the optimal HTL solvent.

Main Results:

The optimized solvent selection procedure successfully identified cyclopentanone (CPO) as a suitable HTL solvent.
Devices fabricated using CPO exhibited a ≈1.6-fold increase in maximum luminescence compared to those using chlorobenzene.
A ≈12.6-fold improvement in maximum current efficiency was observed with CPO compared to conventional hazardous solvents.

Conclusions:

Solvent selection is a critical factor for developing green and high-performance inverted QD-LEDs.
The developed procedure effectively balances device performance with environmental safety.
The findings are particularly relevant for large-scale display manufacturing, including those utilizing n-type oxide thin-film transistors.
