Wide-range temperature sensing using highly sensitive green-luminescent ZnO and PMMA-ZnO film as a non-contact optical probe

Angew Chem Int Ed Engl. 2013 Oct 18;52(43):11325-8. doi: 10.1002/anie.201302449. Epub 2013 Sep 12.

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.

Keywords: ZnO microcrystals; cryogenic thermometry; luminescence; poly(methyl methacrylate); sensors.
