Near‑infrared (NIR) dyes usually hide their brilliance from the human eye, glowing quietly beyond the visible spectrum. Dr Oleg Dimitriev plans to change that story. At the upcoming International Congress on Materials Science & Nanotechnology (MNano 2025), he’ll unveil how carbon dots, plasmonic nanorods, sulfide nanoparticles, and MXene flakes coax NIR dyes to shine vividly from blue‑green to deep red.
1 ▸ What’s the Big Deal?
| Classic Limitation | Dimitriev’s Nano Fix |
|---|---|
| Anti‑Kasha (S₂) emission is too faint to detect | Carbon nano dots anchor dye molecules → 10× jump in blue‑green fluorescence |
| Anti‑Stokes signals are weak | Silica‑coated gold nanorods & Cu₂‑ₓS@MSN align plasmon bands with dye emission → up to 50 % NIR boost |
| Hot‑band absorption hard to tune | MXene nanoflakes with custom thermal emissivity act as nanoscale “thermostats” |
2 ▸ How Could This Help?
-
Energy Up‑Conversion — harvest NIR waste light and convert it to visible.
-
Solar‑Cell Sensitizers — broaden sunlight capture for higher efficiency.
-
Smart Optical Sensors — temperature‑controlled MXene systems adjust signal in real time.
-
NIR/UV Displays — imagine night‑vision signage or covert communication panels.
