Embodiment 1

[0015] First prepare the molar percentage as 20Na 2 O 6CaO 70SiO 2 4PbO 0.01Au 2 o 3 glass. Using quartz sand, soda ash, calcium carbonate, lead oxide and chloroauric acid as main raw materials, first weigh 42.0 grams of quartz sand, 21.2 grams of soda ash, 6.0 grams of calcium carbonate, 8.93 grams of lead oxide and 0.039g of gold chlorate, and the above The raw materials are fully ground and mixed, placed in a quartz crucible or a platinum crucible, and placed in a high-temperature furnace; melted at 1500 ° C for 2 hours to melt the raw materials into a liquid state and mix the molten materials evenly. After heating the molten material at constant temperature for 2 hours, take out the crucible from the high-temperature furnace, quickly pour the molten material in the crucible onto the preheated mold to form a glass sample, put the glass sample into a furnace at 500°C, and slowly cool down and anneal for 24 hours After the annealed glass is cut and polished, the colorless...

Abstract

The invention discloses a dichroic nanogold-particle-doped glass and a preparation method. The preparation method comprises the following steps: synthesizing gold-doped colorless and transparent glass at high temperature; carrying out secondary heat treatment at 500-600 DEG C; preparing glass doped with even purple gold particles the particle diameter of which is at nanoscales; finally, after the irradiation function of femto-second lasers, obtaining functional optical glass with different absorption coefficients to polarized light with different vibration directions.

Description

technical field [0001] The invention relates to a glass doped with nano-gold particles and a preparation method thereof, in particular to a functionalized optical glass doped with nano-gold particles that produces dichroism by femtosecond laser irradiation and a preparation method thereof. It is used in optical devices such as polarizing cavities, photodiodes, and amplifiers. Background technique [0002] The use of glass doped with precious metal elements to design various nano or micro structures has very important guiding significance for the synthesis of advanced materials and optical research. In recent years, based on the characteristics of surface plasmon resonance (SPR) and enhanced third-order nonlinear optical coefficients of nano-precious metal particles, glass materials such as gold and silver have great potential in the fields of nonlinear materials, optical components, and nano-optoelectronic devices. Its application prospects make it attract more and more peo...
