Ultrasonic Spray Deposition

Ultrasonic spray coating as deposition technique for the light-emitting layer in polymer LEDs

In this work the ultrasonic spray coating technique is introduced as an alternative wet solution process for the deposition of the (Super Yellow) light-emitting layer for polymer light-emitting diodes (PLEDs). An investigation on the use of this coating technique in ambient conditions is performed and a comparison with spin coated PLEDs in inert atmosphere is made. Uniform low roughness thin films with a typical thickness of 80 nm are obtained by varying the polymer–solvent mixture and spray coater parameters. PLEDs are produced and reach a luminous power efficacy in the order of 10 lm/W. Through the use of various optical and analytical techniques it is demonstrated that the applied ultrasonic atomization has no noteworthy influence on the original properties of the polymer and on the resulting PLED’s efficacy. Ultrasonic spray coating is therefore a viable deposition technique for the production of PLEDs.

Ultrasonic Coating Solutions for Advanced Battery Research and Emerging Production

Cheersonic’s ultrasonic spray systems enable precision deposition of Advanced Battery Coatings for next-generation energy storage technologies — including lithium-ion (Li-ion) batteries, solid-state batteries, sodium-ion platforms, and emerging aluminum-ion battery (AIB) research. Our ultrasonic atomization process delivers exceptionally uniform, thin film coating layers across electrodes and separators, supporting breakthroughs in cell performance, battery safety, durability, and long cycle life.

Cheersonic systems are designed for precision thin-film and alternative-material coating, including light, low-solids composite slurries, rather than conventional high-solids thick slurry processes. Our technology excels in R&D and emerging production where coating uniformity, low waste, porosity control, and micron-level thickness repeatability are essential.
