| The luminescence characteristics of Eu3+ ions in Eu(NO3)3·6H2O salt contained in polymer films coating the silver metallic surfaces were studied. The surfaces were specially prepared to consist of silver tip arrays with the height of tips in micron and surface density in 10-8 cm-2 ranges. The evaluation of enhancement per one europium ion gave a value 3.5 102 for one polymer layer coating of tip array silver surface in comparison with the case of glass substrate coating. |
