Problems solved by technology

But contrary to expectations, not only did not increase the up-conversion luminous intensity of blue-green light, but also a phenomenon of fluorescence quenching occurred, and the intensity of blue-green light was greatly reduced, such as figure 1 shown
This is due to the Er 3+ and Tm 3+ There is a cross-relaxation phenomenon between ions, so that the excitation energy is converted into heat energy in the form of non-radiative transition between ions, resulting in a decrease in the upconversion luminescence intensity

Abstract

The invention discloses a laminated glass material capable of realizing simultaneous emission of blue, green and red colors without reducing the intensity of blue-green light up-converted by rare earth ions. The glass material is composed of two or more glass materials doped with two different ions, one of which is doped with Yb 3+ / Er 3+ , another glass material doped with Yb 3+ / Tm 3+ . Compared with adding multiple kinds of rare earth luminescent ions to the same matrix material, the invention avoids fluorescence quenching between rare earth ions and improves up-conversion luminous efficiency. Especially in the three-dimensional display, the graphics formed by the light emitted at different thicknesses of the glass have a more three-dimensional display effect, and the present invention has a remarkable application prospect.

Description

technical field [0001] The invention relates to a laminated glass material, in particular to a laminated glass material capable of simultaneously emitting blue, green and red colors without reducing the intensity of up-converted blue-green light by rare earth ions. Background technique [0002] Blue-green band lasers can be widely used in high-density data storage, submarine communication, large-screen display (full-color display with blue-green light structure), detection and laser medical treatment. For example, in optical disc storage, using short-wavelength blue-green laser instead of red light "reading and writing head" can increase the capacity of the existing optical disc by about 4 times; in laser printing equipment, blue-green laser can improve printing speed and resolution ; In submarine communication, the blue-green laser has become a window for underwater transmission because of its excellent penetrating ability to seawater and so on. Especially in three-dimensi...
