Starting with a calculated amount of Quantum Dot 

precursor (LOREX Modification E-12-0002) add the 

specified amount of aminosilicone and toluene to 

Schlenk flask containing nanocrystals in toluene in the

Pour the 20g sample into the smaller well of a 50mL 

cartridge. Pour Epoxy Part A into the larger well of the 

50mL cartridge to about the same level and close both 

wells. Dispense cartridge into a thinky cup to level the 

two sides and to remove the air from the cartridge. 

Dispense about 4g of mixed material into a thinky cup 

and wait the required aging time for the sample. 

Dispense aged sample onto film and wait an additional 

aging time. Coat film using the roller apparatus. All steps 

must be completed for all samples from previous step.
