Investigations of blue emitting phosphors for thermometry

Särner, Gustaf LU ; Richter, Mattias LU and Aldén, Marcus LU (2008) In Measurement Science & Technology 19(12).
Abstract
Blue emitting phosphors are investigated and reported for possible use in thermometry. Currently reported thermographic phosphors in general have the drawback of long emission lifetimes obstructing the possibility to time gate for background discrimination. An additional problem is that many thermographic phosphors have emission in the red spectral region, making them vulnerable for black body radiation at high temperatures. This work reports the temperature sensitivity for nine phosphors considered suitable for accurate temperature measurements in harsh conditions both in single points and in two dimensions (2D).
