Importance of understanding structure-property relationships in Feldspar for Radiofluorescence dating


Importance of understanding structure-property relationships in Feldspar for Radiofluorescence dating

Sharma, S. K.; Fuchs, M.; Heitmann, J.; Gloaguen, R.

Feldspar is a common mineral that has been used efficiently for the past few decades for luminescence dating. The process of separation of Feldspar from rock mineral is a time consuming process, and requires an expertise with different chemical processes. The luminescence properties in Feldspar are controlled by the presence/absence of defect in the host lattice. In the present talk, i will discuss about the different defects, luminescence properties, and their dependence on the crystal structure of Feldspar. The work is carried out on three different samples, currently being used for radio-fluorescence dating.

Keywords: Feldspar; optical properties; luminescence dating; ESR
