Embodiment 1

[0040] Get coumarin compound coumarin 307 (Acros company) 0.1mmol, be dissolved in the ethanol solution of 10ml, be mixed with 10 -2 mol / L solution, the porous glass whose pore volume accounts for 25% of the total volume of the luminescent glass is immersed in the above solution for 8 hours and then taken out, the surface is washed with ethanol solution and dried to obtain a porous luminescent material containing organic fluorescent materials. Glass. For the excitation and emission spectra of the porous luminescent glass prepared in this example, see figure 1 ,from figure 1 We can see that the material is suitable for 450nm blue LED excitation and can emit 500nm green light.

Embodiment 2

[0042] Get rhodamine compound rhodamine 6G (Acros company) 0.01mmol, be dissolved in the ethanol solution of 100ml, be mixed with 10 -4 mol / L solution, the porous glass whose pore volume accounts for 25% of the total volume of the luminescent glass is immersed in the above solution for 8 hours and then taken out, the surface is washed with ethanol solution and dried to obtain a porous luminescent material containing organic fluorescent materials. Glass. figure 2 The emission spectrum of the porous luminescent glass prepared in this example under the excitation of excitation light with a wavelength of 485nm is given, and yellow light of 565nm can be emitted under the excitation of light with a wavelength of 485nm. The test was carried out with Shimadzu RF-5301PC fluorescence spectrophotometer under the condition of 1.5nm slit and low sensitivity.

Embodiment 3

Abstract

The invention provides luminescent glass, a making method and application thereof. The making method comprises the following steps of, firstly, dissolving organic fluorescence materials in a solvent to form an organic fluorescence material solution; secondly, immersing porous glass into the organic fluorescence material solution, and absorbing the organic fluorescence material solution; and thirdly, taking out the porous glass immersed with the organic fluorescence material solution, and drying to prepare the luminescent glass. The luminescent glass is prepared by the method and can be matched with a semiconductor light emitting diode within a range of 200-550 nm to make a light emitting device. The making method of the luminescent glass has simple making technology, and the luminescent glass prepared by the method can be directly applied to the light emitting device of the semiconductor light emitting diode as fluorescence conversion substances and packaging materials, thereby solving the problem of photochemical reaction between the organic fluorescence materials and the organic packaging materials.

Description

technical field [0001] The invention relates to the technical field of luminescence and display, in particular to a method for manufacturing luminescent glass, luminescent glass made by the method and applications thereof. Background technique [0002] With the development of semiconductor lighting technology (LED), this revolutionary new light source has gradually entered our daily life. Using the third-generation semiconductor material gallium nitride as the semiconductor lighting source, the power consumption is only 1 / 10 of that of ordinary incandescent lamps at the same brightness, and the life span can reach more than 100,000 hours. As a new lighting technology, LED has many advantages such as energy saving, green environmental protection, and flexible application. It can be widely used in various indications, displays, decorations, backlights, and general lighting. This will trigger a revolution in the lighting field. [0003] At present, the production method of whi...
