Title: Omer Dag and Fast Luminescent Silicon

Introduction

Omer Dag is an inventor associated with the University of Toronto in Toronto, Canada. His patent work includes research into silicon clusters in mesoporous silica and their potential use in optoelectronic devices.

Latest Patents

Dag is associated with 1 patent, titled “Fast Luminescent Silicon.” The invention describes mesoporous silica materials containing stabilized silicon clusters no larger than 2 nanometers. These clusters can emit fast photons through photoluminescence.

The patent describes forming the clusters by chemical vapor deposition into mesoporous silicate films. The process uses relatively low temperatures, around 100–150°C, and leaves template residues in the films to help limit cluster size. The resulting films are described as air-stable, with silicon clusters anchored in the mesopores, and suitable for potential use alongside standard silicon semiconductors in optoelectronic devices.

Career Highlights

Dag’s documented patent contribution focuses on controlling the size and stability of silicon clusters within porous materials. The approach combines mesoporous film structures with deposition conditions intended to preserve the template residues that constrain cluster growth.

Collaborations

The patent work is associated with Geoffrey Alan Ozin and Hong Yang. Dag’s institutional affiliation is the University of Toronto.

Conclusion

Omer Dag’s patent on fast luminescent silicon describes a method for producing small, stable, photoluminescent silicon clusters in mesoporous silica, with potential applications in optoelectronics.
