The invention discloses a red and blue light photosynthetic light-conversion capable of being activated by blue-violet light and a high-temperature industrial microwave founding method, and belongs to the technical field of optical glass. The glass comprises the following major components by mass percent: 40 to 45% of SiO2, 45 to 40% of B2O3, and 15 to 5% of BaO; and luminous ions are added in the form of Eu2O3 and MnCO3, wherein 0.1 to 0.4% of Eu2O3 and 0.5 to 2% of MnCO3 are added by calculating based on the mass percent of the sum of the main components; and the microwave founding method comprises the following steps of: mixing raw materials; founding with microwave; and then obtaining the photosynthetic light-conversion glass after the heat treatment. The glass cannot be devitrified when in high-temperature industrial microwave founding and cooling, and is high in transparency, stable in chemical performances, wide in emission spectrum bandwidth, and adjustable in proportion of radiation intensity of orange-red light and blue light.

Description

Technical field [0001] The invention belongs to the technical field of optical functional glass, and relates to an optical glass. More specifically, it relates to a photosynthetic light-converting glass capable of simultaneously emitting orange-red and blue light under the irradiation of blue-violet light and a high-temperature industrial microwave melting method thereof. Background technique [0002] The light wavelengths required for plant photosynthesis usually include blue light from 400 nm to 500 nm, red light from 620 nm to 680 nm and far-red light from 720 nm to 740 nm, which have the above effects on the phototaxis, photosynthesis and photomorphogenesis of plants. The red and blue synchrotron radiation corresponding to the band is called photosynthetically active radiation. At the same time, a light source with a characteristic wavelength of 660 nanometers of red light and 450 nanometers of blue light can significantly improve the photosynthetic quantum yield of plant grow...

Problems solved by technology

Among these artificial light sources, traditional light sources include high-pressure sodium lamps and fluorescent lamps, which have the disadvantages of spectral mismatch and energy consumption. New light sources include semiconductor lighting technology represented by LED and the conversion of light-emitting materials to meet the required light. Environmental requirements

Among them, powdered light-transforming luminescent materials that meet the requirements of orange-red and blue light in a wide spectral band are usually compounded in plastic films. The luminescent materials and plastic films are easy to deteriorate and are not easy to recycle. The use of organic complex light-converting materials also has the same shortcomings.
