Area of Science:

• Materials Science
• Analytical Chemistry
• Electrochemistry

Background:

• Electroluminescence (ECL) signal is influenced by electron transfer efficiency.
• Nanomaterial structure affects electron distribution, impacting electron transfer and ECL intensity.
• Increased nanomaterial crystallinity typically enhances electron distribution and conductivity.

Purpose of the Study:

Main Methods:

• Utilizing graphitic carbon nitride as a reporter in an ECL system.
• Correlating ECL signal intensity with the crystallinity of layered double hydroxides (LDHs).
• Validating the technique using Cadmium Aluminum LDHs (CdAl-LDHs) and Zinc Aluminum LDHs (ZnAl-LDH) samples.

Main Results:

• A direct proportionality was observed between the ECL signal and the crystallinity of LDHs.
• An ECL-based approach for crystallinity analysis was successfully established.
