Enhanced UV light emission for opto-electronics

OTT1828

Applications

Photonics, Optoelectronics, Plasmonics, Biosensing, and Medical Diagnostics

Target Problems

Photoluminescence (PL) enhancement and related development of low-cost, strongly UV-light emitting materials are of central importance to advancing many fields of research. Best solutions on the market are produced at a slow rate and at high-cost.

Key Features

• Simple – single step, low-temperature fabrication
• Quick – hydrothermal fabrication is not time intensive
• Superb exhibit – Ohmic I-Vs and electronic semiconductor-like charge transport characteristics

Technology

Inventors at the University of Wisconsin-Milwaukee have developed an easy single-step hydrothermal fabrication method to produce opto-electronic grade, layered zinc phosphate hydrate films onto copper metal substrates. These hydrate films have been confirmed to be mechanically and chemically robust while also demonstrating a spectrally narrow room-temperature UV luminescence band at significant wavelengths, which has potential to impact low-cost solid-state short-wavelength light sources and sensors.
