Optical properties of Eu2+-activated orthosilicates and orthophosphates

Autor: W. Janssen, G. Blasse, S. H. M. Poort

Publikováno v: Journal of Alloys and Compounds. 260:93-97

The luminescence of Eu2+ in Ba2SiO4, Sr2SiO4, KBaPO4 and KSrPO4 has been studied. Luminescence measurements in the temperature range from 4.2 K to 550 K were performed and gave detailed information on the luminescence properties of divalent europium

On the luminescence of GdF3 : Ce3+, Mn2+

Autor: S. H. M. Poort, G. Blasse, Andries Meijerink

Publikováno v: Solid State Communications. 103:537-540

The luminescence of divalent manganese in GdF 3 : Ce 3+ , Mn 2+ has been studied. Excitation in the absorption band of Ce 3+ results in a green Mn 2+ emission with a maximum at 520 nm at 4.2 K. Upon Ce 3+ excitation, energy transfer takes place to Mn

The Luminescence of Mn2 + ‐Activated ZnGa2 O 4

Autor: G. Blasse, S. H. M. Poort, D. Cetin, Andries Meijerink

Publikováno v: Journal of The Electrochemical Society. 144:2179-2183

The luminescence of ZnGa 2 0 and ZnGa 2 0 doped with divalent manganese was studied by performing excitation, emission, and decay time measurements in the temperature range from 4.2 to 500 K. From the results of these measurements the following mecha

Autor: S. H. M. Poort, G. Blasse, H. O. T. Van Der Kuip, H. M. Reijnhoudt

Publikováno v: Journal of Alloys and Compounds. 241:75-81

The luminescence of Eu2+ in (Ca,Sr), MgSiO2O7, MSiO4 (M, Ba, Sr, Ca). BaSi2O7, BaMgSiO4, CaMgSiO4 and Sr2LiSiO4F has been studied. In these structures there are chains of alkaline earth ions. In some cases the Eu2+ ion in these chains shows emission

Influence of Impurities on the Luminescence Quantum Efficiency of the Lamp Phosphor ( Ce , Gd , Tb ) MgB5 O 10

Autor: W. van Schaik, J. J. H. Schlotter, G. Blasse, E. Dorrestijn, S. H. M. Poort

Publikováno v: Journal of The Electrochemical Society. 141:2201-2207

The influence of impurities on the luminescence quantum efficiency of Ce 0.2 Gd 0.6 Tb 0.2 MgB 5 O 10 has been studied. Low concentrations of Pr 3+ , Nd 3+ , Dy 3+ , Ho 3+ , and Er 3+ do not compete efficiently with Gd 3+ and Tb 3+ for the excitation
