Article Synopsis
- - A new force sensor has been developed that combines plasmonic nanostructures with upconversion nanoparticles (UCNPs), featuring a gold nanodisk and a flexible polymer layer.
- - The sensor works by changing its luminescence intensity when compressed or stretched, due to alterations in the polymer thickness affecting how the gold nanodisk interacts with the UCNPs.
- - It offers significantly improved sensitivity compared to older sensors, can be made as either an array for on-chip use or in a fluid form, making it versatile for applications in areas like biology and robotics.
Plasmonic nanostructures can be used to enhance the efficiency of upconversion nanoparticles (UCNPs) and enable new functionalities. However, the fabrication of these hybrid plasmon-UCNP nanostructures has traditionally relied on either wet chemistry or nanolithography routes that are difficult to control, scale up, or both. In this work, we present a scalable nanofabrication process, capable of producing a massive array of gold-UCNP hybrid nanostructures over a few mm area and with excellent uniformity in the photoluminescence intensity.
