• To utilize the color selectivity of digital cameras for ECL signal resolution.

Main Methods:

• Exploiting distinct excitation and emission properties of concomitant electrochemiluminophores.
• Utilizing the inherent color selectivity of a conventional digital camera.
• Resolving red, green, and blue emitters in a 3D space (ECL intensity vs. applied potential and emission wavelength).

Main Results:

• Successfully resolved red, green, and blue emitters.
• Demonstrated effective isolation of single emitter signals at specific potentials.
• Established a constant relative contribution ratio of each emitter to photographic RGB channels.

Conclusions:
