Sulfide-based luminescent materials have attracted a lot of attention for a wide range of
photo-, cathodo-and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the …

fd-excitation, absorption, reflection, and df-emission spectra presented in the literature on
Eu2+ in inorganic compounds have been gathered and re-analyzed. Emission wavelength …

The present invention relates to a tri-color lamp for gener ating White light. In particular, the
invention relates to a phosphor mixture comprising tWo phosphors having host sul? de …

A method of fabricating a light emitting device includes providing a light emitting diode that
emits primary light, and locating proximate to the light emitting diode a (Sr 1− u− v− x Mg u …

The optical properties of rare earth ions in different inorganic host materials, for instance
oxides, silicates, borates, or nitrides, have been used in applications for many years, from …

A photoluminescence study of the blue-green emitting BaGa2S4: Eu2+ phosphor is
reported. Diffuse reflectance, excitation and emission spectra were examined with the aim to …

Solid-state lighting (SSL) is emerging as a highly competent field and a possible alternative
to existing lighting technologies. Development of a suitable phosphor is an important aspect …

In the presented review paper, new potentially interesting material family, RE-doped ternary
sulfides ALnS 2 (RE= Ce, Pr, Sm, Eu, Tb, Tm; A= Rb, K; Ln= La, Gd, Lu, Y) is discussed …

Luminescence, decay, and thermal quenching under photonic excitation of mono and
polycrystals have been measured. For excitation into the lower 5d states, thermal quenching …

The photoluminescent (PL) emission and excitation behaviour of green-emitting CaAl2S4:
Eu2+ powder phosphor is reported in detail. CaAl2S4: Eu2+ emission provides good CIE …
