Embodiment

[0046] According to the molecular formula (La 0.757 Er 0.003 T m 0.04 Yb 0.2 )(Zr 0.05 Ti 0.95 ) 2.25 o 6 For batching, weigh six kinds of oxide powders according to the mass ratio, mix them evenly, use alcohol to wet grind twice, then calcinate the mixed powder, the atmosphere is air, cool with the furnace, and then press the powder into a columnar round tablets, the weight of each tablet is 60-80mg, and the pressure is 5-9MPa. Finally, put the wafer into the nozzle of the air-suspension containerless equipment, use laser to melt and solidify the wafer without container, the gas flow is oxygen, and the laser power is 60-90W. After the sample is completely melted into a spherical shape and uniform, quickly Turn off the laser and obtain ellipsoidal or spherical heavy metal oxide glasses. The glass is polished on both sides to obtain a glass disc with a thickness of 1.5 mm, and then the up-conversion fluorescence spectrum of the glass sample is measured under 980 nm cont...

Abstract

The invention relates to a heavy metal oxide block glass material for up-conversion of white light and a method for enhancing the illumination intensity of the heavy metal oxide block glass material. The heavy metal oxide block glass material for the up-conversion of the white light consists of the following components in percentage by mass of the glass material: 47wt% to 49wt% of TiO2, 30wt% to 44wt% of La2O3, 3wt% to 4wt% of ZrO2, 0.1wt% to 1.1wt% of Er2O3, 0.3wt% to 6.1wt% of Tm2O3 and 2.7wt% to 11.2wt% of Yb2O3, wherein the sum of the mass percentages of the components is 100%.

Description

technical field [0001] The invention belongs to the technical field of luminescent materials, and in particular relates to a white light up-conversion luminescent heavy metal oxide block glass material and a method for improving the up-conversion luminous intensity. Background technique [0002] In the 1960s, people successfully developed light-emitting diodes (LEDs) by using the principle of semiconductor PN junctions to emit light. Since the invention of LED, it has been widely used in the fields of signal indication, display screen, backlighting and outdoor landscape. In addition, for general lighting, white LED light source has more practicality and commercial value. White light LED has many advantages such as high luminous efficiency, low power consumption, long life, energy saving and environmental protection, so it is unanimously considered to be the third-generation lighting source that is expected to replace traditional lighting fixtures such as incandescent lamps a...
