This work presents the investigation about the structural and optical properties of a doped-chromium system containing cordierite (Mg 2 Al 4 Si 5 O 18 ) as main phase. The sample composition and the structural data were obtained from X-ray diffractio

In this work, we revisit and show how the structural and photoluminescent properties of the MgGa2O4 ceramic compound have been kept unchanged for more than two decades. The obtained results confirm the high quality, radiative efficiency, and chemical

We present the photoluminescence, excitation and photoacoustic spectra at room temperature of the system MgGa 2 O 4 –Ga 2 O 3 doped with Cr 3+ . The samples were prepared by solid state reaction and their formation was verified by X-ray diffraction

We study the evolution of an inhomogeneous fluid with self-similarity of the second kind and anisotropic pressure. We found a class of solution to the Einstein field equations by assuming an equation of state where the radial pressure of the fluid is

Photoluminescence, absorption and excitation spectra of K{sub 2}LiAlF{sub 6} single crystals doped with 1% of Cr{sup 3+} are presented. The near-infrared photoluminescence observed at room temperature, 77 and 4 K are attributed to the zero-phonon spi

In this paper we present the photoacoustic spectroscopy of ZnGa2O4 with 5 and 10% of Fe3+. The ZnGa2O4 is a normal spinel, with Zn2+ ions in tetrahedral sites and Ga3+ ions in octahedral sites. It is expected for these hosts that Fe3+ ions occupy Ga3

Optical materials that emit from the visible to the near-infrared spectral region are of great interest due to their possible application as tunable radiation sources, as signal transmission, display, optoelectronics signal storage, cellulose industr
