Time Division Colorful Multiplexing Based on Carbon Nanodots with Modifiable Colors and Lifetimes. | LitMetric

AI Article Synopsis

  • - Optical multiplexing is used in areas like data storage and biological imaging, but single-wavelength methods can cause interference and data misinterpretation due to overlapping emission peaks.
  • - The paper introduces a colorful multiplexing approach using phosphorescent carbon nanodots, which use different colors and lifetimes to represent varying levels of information.
  • - This method allows encoding more complex information and increases storage density by assigning different data bits to each color, improving both encryption security and data compactness.

Article Abstract

Optical multiplexing technology plays a crucial role in various fields such as data storage, anti-counterfeiting, and time-resolved biological imaging. Nevertheless, employing single-wavelength phosphorescence for multiplexing often results in spectral overlap among the emission peaks of various channels, which can precipitate crosstalk and misinterpretation in the information-decoding process, thereby compromising the integrity and precision of the encrypted data. This paper proposes a time-divided colorful multiplexing technology based on phosphorescent carbon nanodots with different colors and lifetimes. Using different luminescence colors to symbolize varying information levels helps achieve multitiered information encryption and storage. By modulation of the lifetime and the emission wavelength, intricate information can be encoded, thereby enhancing the intricacy and security of the encryption mechanism. By assigning different data bits to each color, more information can be encoded in the same physical space. This method enables higher-density information storage and fortifies encryption, ensuring the compactness and security of information.
