| Abstract: | The effect of the crystal structure upon the luminescence of the divalent europium within the RbLu3F10 dimorphous matrix has been investigated. The obtained results essentially show that the difference between the rubidium coordination numbers in both α- and β-RbLu3F10 phases (15 or 16 and 8 or 10 respectively) is responsible for the change over from a 4f7 → 4f7 emission to a 4f65d1 → 4f7 emission. |
