Example Embodiment

[0013] Example 1:

[0014] Weigh the components of the glass composition according to the following molar percentages:

[0015] ZnO: 69.00%; B 2 O 3 : 30.99%;

[0016] MnCO 3 : 0.01%.

[0017] The raw material components accurately weighed according to the composition ratio are ground and mixed and put into a crucible, and carbon powder is put into the furnace as a reducing atmosphere, and the temperature is kept at 900°C for 5 hours. After the glass is out of the furnace, it is poured into a stainless steel mold for molding, and then annealed in an air atmosphere at 500°C for 4 hours, and then naturally cooled to room temperature to obtain a colorless and transparent long afterglow glass; after 20 minutes of irradiation with a 254nm UV lamp, the glass has a red afterglow Up to 12 hours.

Example Embodiment

[0018] Example 2:

[0019] Weigh the components of the glass composition according to the following molar percentages:

[0020] ZnO: 69.00%; B 2 O 3 : 30.99%

[0021] MnCO 3 : 0.01%.

[0022] The raw material components accurately weighed according to the composition ratio are ground and mixed into a crucible, and hydrogen is introduced into the furnace as a reducing atmosphere, and the temperature is kept at 1500°C for 0.5h. After the glass is out of the furnace, it is poured into a stainless steel mold for forming, and then annealed in an air atmosphere at 450°C for 5 hours, and then naturally cooled to room temperature to obtain a colorless and transparent long afterglow glass; after 20 minutes of irradiation with a 254nm UV lamp, the glass has a red afterglow Up to 12 hours.

Example Embodiment

[0023] Example 3:

[0024] Weigh the components of the glass composition according to the following molar percentages:

[0025] ZnO: 34.00% B 2 O 3 : 65.00%

[0026] MnCO 3 :0.10% Zn: 0.90%

[0027] The raw material components are accurately weighed according to the composition ratio, ground and mixed uniformly, and then put into the crucible, and kept at a constant temperature of 1400°C for 1 hour in an air atmosphere. After the glass is out of the furnace, it is poured into a stainless steel mold to form, and then annealed in an air atmosphere at 500°C for 4 hours, and then naturally cooled to room temperature to obtain a colorless and transparent long afterglow glass; after 20 minutes of irradiation with a 254nm UV lamp, the glass has a red afterglow Up to 12 hours.

Abstract

The present invention provides a preparation method of red or green long persistence glass by using zinc borate as matrix. Said invention uses zinc oxide and boron oxide as glass matrix, the luminous ion manganese or terbium can be doped in said glass matrix, in the reduction atmosphere or under the air atmosphere in which the reducing agent elementary zinc is added the above-mentioned materials are molten at 900-1500deg.C and constant temperature is retained for 0.5-5hr, so that the invented product can be obtained. After said long persistence luminescent glass is irradiated for 20 min. by 254nm UV lamp, it can produce red long persistence light whose emissive wavelength is 600nm and green long persistence light whose emissive wavelength is 542nm, the persistence time can be respectively up to 12h and 8h.

Description

technical field [0001] The invention relates to a preparation method of red and green long afterglow glass with zinc borate as the glass matrix. technical background [0002] Long afterglow material is a new type of energy material and energy-saving material. The generation of long afterglow is due to the existence of traps with suitable energy levels and depths in the material, which store excitation energy and release it slowly in the form of light according to a certain dynamic law. Utilizing the light storage-luminescence characteristics of long afterglow materials can be widely used in various aspects of production and people's lives. At present, there are three main uses of long afterglow luminescent materials: low-level emergency lighting, indicator marks and decoration and beautification. Most of the long afterglow materials reported at home and abroad are polycrystalline powders, and there are few reports on long afterglow glasses, and they are mainly long aftergl...
