Connecticut Patent of the Month – February 2024

In the ever-evolving realm of semiconductor devices, the innovators at Saphlux, Inc. have been granted a patent for an invention that promises to reshape the landscape of light conversion technology. The patented light conversion device, a testament to their commitment to pushing boundaries, boasts a porous structure comprising cutting-edge nanoporous materials and an array of quantum dots meticulously placed within.

At its core, the device leverages the properties of quantum dots to optimize light conversion. The nanoporous materials, forming a matrix structure of glass, plastic, or polymer, house a multitude of nanoscale-sized pores. Quantum dots, strategically positioned within these pores, create a symphony of color transformation.

The quantum dots in the first layer are tailored to convert light of a specific color into captivating red hues, while those in the second layer work their magic, transforming the same light into vibrant greens. The result? A visual spectacle where a single device effortlessly produces red, green, and blue light, paving the way for a spectrum of applications in lighting, displays, and beyond.

The brilliance of Saphlux’s invention extends to the fabrication process. Employing a method that involves etching solid materials—ranging from semiconductors like Si, AlN, InGaN, or AlGaN, to glass, plastic, metal, or polymers—the porous structure comes to life. The meticulous placement of quantum dots within the nanoscale pores ensures precision in color conversion.

The implications of this invention are far-reaching. From enhanced display technologies to energy-efficient lighting solutions, Saphlux’s light conversion device opens new avenues for exploration. Violet light, emitted by a light source like a light-emitting diode or laser diode, becomes a canvas for a vivid play of colors—reds, greens, and blues.
