example 1

[0034] Example 1, photo-red luminescent glass and its production method:

[0035] The formula (percentage by weight) of the light-induced red luminescent glass: the glass frit accounts for 85%, assuming as

[0036] 85KG. The red combination luminescent material accounts for 15%, which is 15KG.

[0037] The red combined luminescent substance is calculated according to its ratio, and the weight of each component is: (1) SiO 2 3 (26.5%)

[0038] 3.975KG, Al 2 o 3 (7%) 1.05KG, B 2 o 3 (10%) 1.5KG, (2) Na 2 O(10%)1.5KG,

[0039] K 2 O (7%) 1.05kg, SrCO 3 (8%) 1.2KG, (3) NH 2 (9.5%) 1.425KG, Tb 2 o 3 (6.5%)9.75KG

[0040] , Er 2 o 3 (8.5%) 1.275KG, (5) La 2 o 3 (7%) 1.05KG.

[0041] Production method: According to the first production method.

example 2

[0042] Example 2, the production of photomulticolor (orange, yellow, green) luminescent glass.

[0043] The prescription of photomulticolor (orange, yellow, green) colored light-emitting glass: glass frit accounts for 91%, assumes and gets as 91KG, and orange, yellow, green combination luminescent thing accounts for 9% altogether, is 9KG.

[0044] According to the combination of orange luminescent substances accounted for 3KG; yellow combined luminescent substances accounted for 3KG; green combined luminescent substances accounted for 3KG.

[0045] According to the above weight, weigh the component content of each color combination luminescent material. According to the first step of the second production method, powder materials of combined luminous substances of various colors are produced respectively. Then press the second step to produce luminescent glass with orange, yellow and green colors.

example 3

[0046] Example 3, the production of luminescent glass with partial blue color luminescence.

[0047] Get ready material by the prescription of example one, produce by the 3rd production method.

Abstract

The invention discloses a colour photoluminescence glass and its production method, which comprises 85-92% of glass material and 8-15% of compound luminescent material, and the composition of compound luminescent material includes: (1). one or several kinds of SiO2, Al2O3, B2O3; (2) one or several kinds of Na2O, LiO, K2O and SrCO; (3). one or two kinds of P2O5 and NH2; (4) one or several kinds of Tb2O3, Eu2O3, Y2O3, Er2O3 and Ce2O3; and (5) one or several kinds of TiCl, Nd2O3, Dy2O3 and La2O3. According to the luminescent colour the said materials can have different combinations and mixing ratio, and its luminescent colour can have various colours of red, orange, yellow, blue and purple, etc. After the natural light can be absorbed by said glass for 10-15 min., it can emit colour light for 6-8 hr.

Description

Technical field: [0001] A photochromic luminous glass and a production method belong to glass. Background technique: [0002] According to the chemical composition of glass, glass can be divided into soda lime glass, lead glass, borosilicate glass and so on. Glass itself cannot emit light, so glass handicrafts and decorations lose their appreciation value in the dark. Some objects rely on the addition of luminous substances to emit light. At the end of the nineteenth century, some radioactive energy elements (such as radium, etc.) were found to emit light. Because it is radioactive, its use is limited. In the 1960s, the ZnS fluorescent luminescent substance was invented, and it has been widely used. Due to the limitation of its own physical properties: short luminous time, fast brightness decay, short service life, and operating temperature below 700°C. Therefore, it can only be used in ceramics, organic synthesis, plastics, printing, etc. The luminous substanc...
