Paper Abstract

A fiber-optic temperature sensor was fabricated and studied by using a tapered optical fiber which is coated with a quantum dots (QDs) doped sol-gel thin films. The CdSe/ZnS core-shell nanocrystals were trapped into sol-gel and coated on a tapered optical fiber. The dependence of photoluminescence (PL) spectrum on temperature change was studied. The sensor response is linear and repeatable to the temperature change.
