Revolutionary MoSe2 Films Convert Infrared Light with 1,500x Efficiency

4/6/2026

Summary

Story summary

Researchers developed molybdenum diselenide (MoSe2) films that trap light in layers over a thousand times thinner than a human hair.
MoSe2 exhibits nonlinear optical behavior and converts infrared light into visible blue light with 1,500 times more efficiency than flat layers.
Researchers produced large, uniform MoSe2 films via molecular beam epitaxy, enabling photonic integrated circuit applications.
The National Science Centre and the European Union funded the research.
