In this paper, synthetically scaled-up degenerately n-type doped indium tin oxide (Sn:In2O3) nanocrystals are described as highly transparent conductive materials possessing both optoelectronic and crystalline properties.With tin dopants serving as n-type semiconductor materials, they can generate free-electron carriers.These free electrons, vibrating in resonance with infrared radiation, induce strong localized surface plasmon resonance (LSPR), resulting in efficient infrared absorption.To commercialize products featuring Sn:In2O3 with localized surface plasmon resonance, a scaled-up synthetic process is essential.To reduce the Gas Range Cooker cost of raw materials during synthesis, we aim to proceed with synthesis in a large reactor using industrial raw materials.

Sn:In2O3 can be formulated into ink dispersed in solvents.Infrared-absorbing ink formulations can capitalize on their infrared absorption properties to render opaque in the infrared spectrum while remaining Gearbox Mounting Frame transparent in the visible light spectrum.The ink can serve as a security ink material visible only through infrared cameras and as a paint absorbing infrared light.We verified the transparency and infrared absorption properties of the ink produced in this study, demonstrating consistent characteristics in scaled-up synthesis.Due to potential applications requiring infrared absorption properties, it holds significant promise as a robust platform material in various fields.
