Rare earth doped anodic Ta 2 O 5 layers can show characteristic light emission. In the case of Eu 3+ photoluminescence, excitation is restricted to common charge transfer and 4f shell transitions. No electroluminescence can be observed. This is diffe

The luminescence properties under high-resolution excitation and emission conditions at 4.2 K of hydrated Gd3+ion-exchanged zeolite A are reported. From these luminescence measurements it is found that in a sample containing 0.8 wt.% Gd3+, only one s

The luminescence properties of the compounds ABO4(A = Sb, Bi; B = Nb, Ta) and ABi2Nb2O9(A = Sr, Ba) are reported. The influence of the ns2 ions on the luminescence properties of the transition-metal oxo-compounds depends strongly on their coordinatio

The red luminescence of bismuth-doped alkaline-earth-metal sulfates is ascribed to the presence of divalent bismuth The optical transitions are due to transitions within the 6p shell.

The luminescences of GaBO3 and LiGaO2 are reported. The former has GaIII in octahedral sites (calcite structure), the latter in tetrahedral sites (ordered wurtzite structure). The GaIII co-ordination number has the same influence on the luminescence

The luminescence properties of rare-earth activated and unactivated Gd2(MoO4)3 and those of Eu2(MoO4)3 and Tb2(MoO4)3 are reported. Gd2(MoO4)3 shows two different molybdate emissions which are assigned to intrinsic and defect molybdate groups. Energy

The luminescence spectra and decay tunes of the emission of the [Cu(PPh3)2(phen)]+ ion have been measured down to liquid helium temperature. The long decay time at low temperatures is interpreted in terms of the triplet level of the charge- transfer
