Abstract

PURPOSE:To obtain the title glass invariant in transparency even if made to be luminescent by sealing an illuminance consisting of a solution of organometallic complex compound in a closed space formed by two sheets of light-transmissive plate glass and a pair of spacers. CONSTITUTION:An illuminant 3 consisting of a solution of a complex compound prepared from e.g., beta-diketone and metal is sealed in a closed space formed by two sheets of transparent plate glass 1,1' and a pair of spacers 2. For the solution of said complex compound, for example, Eu is used as a metal, C5H2F6O2 (1,1,1,5,5,5-hexafluoro-2,4-pentanedione) as a beta-diketone, and acetone as a solvent. The multilayered glass thus obtained can be made to be luminescent by externally applying a stimulus (excitation light) while retaining its transparency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to double-glazed glass in which other substances, functional materials, etc. are interposed between two sheets of glass.

[Background Art] In recent years, a new use for glass has been developed: double-glazed glass whose state changes when an electrical signal or stimulus is applied from the outside. As glass that changes color from being transparent, there are double-layered glass with electrochromic material that changes color when a voltage is applied, and photochromic glass that changes color when exposed to strong light. Furthermore, double-layered glass is known as a glass that changes from transparent to opaque by sandwiching liquid crystal and applying voltage.

[Problem to be solved by the invention]

As mentioned above, double-glazed glass that changes from a transparent state to another state (opaque or colored) by applying an external electrical signal or stimulus has been researched and developed. Therefore, there is still no double-glazed glass that emits light from a transparent state.

As a partially luminous glass, there is one in which a fluorescent paint is applied to the surface of a plate glass and the fluorescent paint is made to emit light by irradiating it with excitation light from the outside. However, because the fluorescent paint is opaque, the plate glass is white (some are colored).
It will look like it has been painted on, and the translucency of the painted area will be impaired.

The present invention has been made in view of the above points, and its purpose is to provide double-glazed glass that emits light while maintaining the transparency of the glass, in other words, the transparency of the glass does not change even when light is emitted. There is a particular thing.

[Means to solve the problem]

In order to solve the above problems, the double glazing according to the present invention includes:
It is characterized by a luminescent material made of a solution of an organometallic complex compound being enclosed in a closed space formed by two sheets of transparent glass and a spacer, and the two sheets of glass that are transparent are sealed. It is characterized by interposing a luminescent material in which an organometallic complex compound is mixed into a transparent resin that transmits near ultraviolet rays.

[Function] By irradiating near-ultraviolet rays as excitation light from the outside to the double-glazed glass having the above structure, the luminous body emits light while maintaining the transparency of the glass.

[Example] Figure 1 is a cross-sectional view showing an example of the present invention, in which a complex of metal and β-diketone is placed in a closed space formed by two transparent glass plates 1.1° and a spacer 2. A luminous body 3 made of a solution of a compound is enclosed.

In this example, as a solution of the organometallic complex compound, europium (Eu) was used as the metal, and β-diketone C, H, F, O□ (Ll, 1.5° 5.5-H) was used as the organic substance.
exafluoro-2,4-pentanedion
e),? Acetone (CH3COCR3) was used as a container. Further, the glass plates 1 and 1° may be formed of a material other than glass that has translucency.

By irradiating the double-glazed glass constructed in this manner from the outside with a black light having an emission spectrum distribution as shown in Figure 3 as excitation light, we were able to emit trivalent europium (U3°). Red light having a peak wavelength near 612 nm is emitted. The emission spectrum distribution is shown in FIG. Note that in FIGS. 3 and 4, the horizontal axis represents the wavelength (n+a), and the vertical axis represents the relative intensity of light emission.

Regarding the emission color, terbium (Tb) is added to the above metal.
), green light emission with an emission spectrum peak around 546 nm can be obtained. In addition, the excitation light is not limited to black light, but also in the near ultraviolet region (
Any material may be used as long as it emits light with a wavelength of 300 nm to 380 nm.

In that case, by changing the type of β-diketone, the optimum combination for the excitation light can be obtained.

Next, different embodiments of the present invention will be described. Figure 2 is a cross-sectional view of the same, and between two transparent glass plates 1 and 1, a luminescent material 4 containing a complex compound of metal and β-diketone mixed (kneaded) into a transparent resin that transmits near ultraviolet rays. This is an intervening method. Even with this configuration, the same effects as the above embodiment can be obtained, and the strength is superior to the above embodiment.

Note that the present invention is not limited to the above embodiments.

For example, although a flat plate was described in the above embodiment, it may be constructed by combining these flat plates, or any structure that can form a multilayer structure as shown in FIGS. 1 and 2. It can be anything. Furthermore, the number of layers is not limited to three.

〔Effect of the invention〕

As described above, the present invention maintains the transparency of the glass by using a luminous material made of a solution of an organometallic complex compound in the intermediate layer of double-glazed glass, or a luminous material made of a transparent resin mixed with an organometallic complex compound. While it is still in place, apply external stimulation (
It is possible to provide double-glazed glass that emits light by applying excitation light.
