Popis: |
Bright luminescence of Eu(II) doped into the cubic perovskites KMgH3 and mixed crystal compounds LiBaxSr(1-x)H(3) was observed and assigned to the 4f(6)5d-4f(7) emission of Eu2+. KMgH3: Eu2+ shows an extremely bright yellow emission, whereas the wavelength of the emission maximum in LiBaxSr(1-x)H(3): Eu2+ depends on the value of x and ranges from yellow to green. Furthermore, an extremely wide red shift in the emission energy is observed for the orthorhombically distorted perovskite NaMgH3: Eu2+. Additionally, we review the crystal structure of KMgH3 using density functional calculations. |
