PPT-Optically Stimulated Luminescence

As sediment quartz is transported by wind water or ice it is exposed to sunlight bleached and zeroed of any previous luminescence signal Once this sediment is deposited and subsequently buried it is removed from light and is exposed to low levels of natural radiation from the surrounding . This effect was explained by Christiaan Huygens 1629 1695 Dutch physicist as double refraction of what he called an ordinary and an extraordinary wave With the help of a polarizer we can easily see what these ordinary and extraordinary beams are Ob Luminescence Scienceand Display Materials Luminescence is Del neD BROADLY As THe γeneRATiOn OF LiγHT in eXcess OF THAT RADiATeD THeRmALLY.
