Abstract

For the deposition of the semiconductor nanocrystals or quantum dots, it is required to have the substrates with smooth surface roughness. Slot-die coating method wad adopted and optimized varying the processing parameters like coating speed, gap distance, solution concentration, etc to get the smooth coated films on flexible substrates. The coating speed in slot-die method was varied from 1 m/min to 2.5 m/min focusing especially on its industrial usage. The gap distance between the substrate surface and slot-die lip was changed also to control mainly the thickness of coated films.
