title: Wide-range temperature sensing using highly sensitive green-luminescent ZnO and PMMA-ZnO film as a non-contact optical probe.
abstract: The heat is on: A variation of green luminescence intensity of ZnO microcrystals embedded in poly(methyl methacrylate) is observed. This material is used for non-contact thermometer, which has an accuracy of 0.1 K over a temperature range of 83-474 K. Scale bars: 10 μm.
