Abstract A significant impediment to the deployment of anti-counterfeiting technologies is the reliance on specialized hardware. Here, anti-counterfeiting labels are developed that are both excited and detected using a smartphone. The persistent lumi

A phosphor-particle-loaded microlens array on a polymer substrate offers an attractive unclonable anticounterfeiting label design. A random pattern of bright emission points is created due to the random coincidences of light focused by a microlens wi

Micron-scale randomness during manufacturing can ensure anti-counterfeiting labels are unclonable. However, this security typically comes at the expense of complex hardware being needed for authentication (e.g., microscopy systems). We demonstrate un

A ratiometric optical thermometer based on triply‐doped La$_{2}$O$_{3}$:Yb$^{3+}$/Er$^{3+}$/Nd$^{3+}$ microcrystals is reported with a relative sensitivity above 1% K$^{-1}$ in the entire range from 300–700 K, and is between 1.8–0.7% K$^{-1}$ o

Thermal images generated from infrared radiation are useful for monitoring many processes; however, infrared cameras are orders of magnitude more expensive than their visible counterparts. Methods that allow visible cameras to capture thermal images
