Title: Monolithic translucent BaMgAl₁₀O₁₇:Eu²⁺ phosphors for laser-driven solid state lighting

Abstract

With high power light emitting diodes and laser diodes being explored for white light generation and visible light communication, thermally robust encapsulation schemes for color-converting inorganic phosphors are essential. In the current work, the canonical blue-emitting phosphor, high purity Eu-doped BaMgAl₁₀O₁₇, has been prepared using microwave-assisted heating (25 min) and densified into translucent ceramic phosphor monoliths using spark plasma sintering (30 min). Lastly, the resulting translucent ceramic monoliths convert UV laser light to blue light with the same efficiency as the starting powder and provide superior thermal management in comparison with silicone encapsulation.

On BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} phosphor degradation mechanism by vacuum-ultraviolet excitation

Journal Article Bizarri, G ; Moine, B - Journal of Applied Physics

Additional to a correct color and a high efficiency, phosphors for plasma display panels must maintain their light output for thousands of hours. Often the degradation is the restricting factor in using phosphors. In this article, the mechanism of luminance decrease in blue-emitting BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} phosphor during the operation of the PDPs has been studied. It is shown experimentally that the aging process is mainly due to the vacuum-ultraviolet excitation (VUV). It is demonstrated that the degradation mechanism can be accelerated by using a 193 nm laser excitation. Based on excitation, reflectance, thermoluminescence spectra, and aging or annealingmore »« less

Mechanism of particle growth of a BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} phosphor by firing with AlF{sub 3}

Journal Article Oshio, Shozo ; Matsuoka, Tomizo ; Tanaka, Shosaku ; ... - Journal of the Electrochemical Society

The mechanism of particle growth of the blue emitting BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} phosphor by firing with AlF{sub 3} has been clarified. It was found that the reaction between BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} and AlF{sub 3} during firing, on the basis of the following chemical equation, results in recreation of BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} with particle growth BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} + (4/3)AlF{sub 3} {l_reversible} BaMgF{sub 4}:Eu{sup 2+} + (17/3)Al{sub 2}O{sub 3}, the firing of Ba/MgAl{sub 10}O{sub 17}:Eu{sup 2+} with AlF{sub 3} first converts the phosphor into a mixture of the two compounds, BaMgF{sub 4}:Eu{sup 2+} and Al{sub 2}O{sub 3},more »« less

Mechanism of luminance decrease in BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} phosphor by oxidation

Journal Article Oshio, Shozo ; Matsuoka, Tomizo ; Tanaka, Shosaku ; ... - Journal of the Electrochemical Society

The mechanism of luminance decrease in blue emitting BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} phosphor after annealing has been studied. It was shown experimentally that annealing in air oxidizes BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} and substantially changes the Eu{sup 2+} ion to an Eu{sup 3+} ion. This is also deactivates the Eu{sup 2+} luminescent center, thus decreasing Eu{sup 2+} emission. Furthermore, the compound EuMgAl{sub 11}O{sub 19}, in which the valence of the Eu ion is trivalent, was detected in BaMgAl{sub 10}O{sub 17}:Eu{sup 2+} annealed at temperatures higher than 800 C as a resulting product of oxidation. It was demonstrated that BaMgAl{sub 10}O{sub 17}:Eu{supmore »« less

A novel blue-emitting phosphor LiSrPO{sub 4}:Eu{sup 2+} for white LEDs

Journal Article Wu, Z C ; Shi, J X ; Wang, J ; ... - Journal of Solid State Chemistry

A novel blue-emitting phosphor, LiSrPO{sub 4}:Eu{sup 2+}, was prepared by the solid-state reaction and X-ray powder diffraction (XRD) analysis confirmed the formation of LiSrPO{sub 4}:Eu{sup 2+}. Photoluminescence (PL) results showed that the phosphor can be efficiently excited by UV-visible light from 250 to 440 nm, and exhibited bright blue emission. The effects of the doped-Eu{sup 2+} concentration in LiSrPO{sub 4}:Eu{sup 2+} on the PL were investigated in detail. The results showed that the relative PL intensity increases with Eu{sup 2+}-concentration increasing until a maximum intensity is reached, and then it decreases due to concentration quenching and a red-shift appears, whichmore »« less
