Use of aluminum nitride for UV radiation dosimetry
Abstract An investigation of AlN ceramics for applications in UV radiation detection shows the advantages of using the 480 nm emission band for optically stimulated luminescence signal detection instead of the previously used 400 nm emission band since the rate of decrease of the response signal at room temperature is lower than that of the 400 nm band, and its excitation region falls in the UV-B range.
UV light energy storage and thermoluminescence in AlN ceramics
AlN ceramics, untreated and subjected to oxygen ion implantation, are studied for potential application in TL dosimetry of UV light. Based on photoluminescence and thermoluminescence measurements there are shown advantages of the selection of the 480 emission band for TL signal recording instead of the previously used 400 nm band: higher intensity of the TL signal, lower fading rate of the accumulated TL signal, excitation region (270-340 nm) corresponding to UV-B range, monitoring of which is actual in UV dosimetry.
