| Abstract: | The nature and source of the background absorption of samarium matrix and the method for elimination of the background were studied. The background absorption of SmCl_3 matrix arises mainly from the absorption of SmCl_3 vapour. The background of Sm(NO_3)_3 matrix has been shown to be a double-peak in the interesting wave length range,coming from the absorption of decomposed-product NO and its oxides. The background absorption of Sm(NO_3)_3 is much smaller than that ot SmCl_2. (?)herefore, it is best to transfer samples to be analyseed into samarium nitrate for decreasing backgrond absorption. |
