[Study on the IR and UV dual-spectrum radiation]

Area of Science:

• Materials Science
• Optics and Photonics
• Chemical Engineering

Context:

• Traditional pyrotechnics primarily emit in the infrared (IR) spectrum.
• Generating simultaneous ultraviolet (UV) radiation alongside IR is challenging.
• Dual-spectrum emitters are valuable for various applications, including signaling and countermeasures.

Purpose:

• To develop a method for producing simultaneous dual-spectrum radiation in both the infrared (IR) and ultraviolet (UV) ranges.
• To investigate the feasibility of combining UV-emitting pyrotechnics with traditional IR pyrotechnics.
• To computationally analyze and experimentally validate the dual-spectrum emission.

Summary:

• Theoretical analysis and computation of relative data were performed.
• Specific atomic materials were selected and incorporated into double-base propellants.
• Simultaneous ignition of UV and IR pyrotechnics resulted in concurrent emission across both spectra.
• Final measurements confirmed the successful generation of dual-spectrum radiation.

Impact:

• This research enables the creation of novel pyrotechnic devices capable of emitting both IR and UV radiation simultaneously.
• The developed method provides a foundation for advanced signaling, illumination, and decoy technologies.
• Satisfying experimental results indicate the practical viability of this dual-spectrum radiation production technique.
