Visible Light Luminescence in Silica-Based Superstructure Films

We measured the visible luminescence, under various conditions, of two different silica based superstructure films mounted on a silica substrate. One superstructure film was made up of alternate nanometer layers of Ge:SiO2, Ti:SiO2 and Sn:SiO2 and the other of Ge:SiO2, Ti:SiO2 and Zr:SiO2.

Fluorescence of Porous Silicon Filled with Liquid Crystal 5CB

In the present research, we consider nanoporous silicon filled with nematic liquid crystal (LC) n-pentyl-n' -cyanobiphenyl (5CB) as a specimen of hybrid systems with high quantum yield of fluorescence (FL). The steady-state and time-resolved FL spectra of this system excited by a nitrogen laser (?

Effects of Molecular Structure on Luminescent Properties of Betaine Dyes

We compared spectral properties of Betaine-30 (B30) with other similar betaines or triphenylpyridine. They showed similar UV-absorption and shorter emission spectra in polymeric solids.

Quenching of Lanthanide Emission by Intervalence Charge Transfer in Crystals Containing Closed Shell Transition Metal Ions

The quenching of the luminescence originating from the excited states 3P0 and 1D2 of Pr3+ and 5D3 and 5D4 of Tb3+ has been studied in oxide crystals containing closed shell transition metal ions, such as titanates, vanadates, niobates, and tantalates.

The VUV-VIS Spectroscopic Properties of Dy3+ Ion in Phosphors M5-2XDyXNaX(PO4)3F (M=Ca, Sr, Ba) and Their Potential Applications in Mercury-Free Lamps

The phosphors, fluorapatites M5(PO4)3F (M=Ca, Sr, Ba) activated with Dy3+ ions, were prepared by a high-temperature solid-state reaction technique. The VUV-UV excitation spectra and emission spectra under VUV/UV excitation were measured.

Nonlinear Luminescence Quenching in Eu2O3

We report a laser spectroscopic investigation of saturation effects in the spectra and dynamics of Eu2O3. The saturation effects occur at high laser intensity and appear as dips in the center of the fluorescence excitation lines and as a shortening of the 5D0 excited-state decay curve.

NANOPHOSPHORS FOR WHITE LIGHT LEDS

In this article, a salted sol-gel and a salted sol-gel combustion method were developed for nanophosphor synthesis. Massive nanophosphor production becomes possible by using these novel methods. Some blue, green, and red LED nanophosphors were prepared by using these novel methods.
