Embodiment 1
[0085] CaF 2 : Preparation of xYb (x=0.1%, 0.5%, 2%, 10%, 30%, 50%) fluorescent cluster materials and their optical properties.
[0086] Weigh a certain amount of CaF according to the molar ratio 2 and YbF 3 , Grind it thoroughly to make it evenly mixed and put it into Al 2 o 3 Porcelain boats or other non-corrosive crucibles are placed in a vacuum environment at 1200°C for 2 hours and then taken out after cooling to room temperature naturally to obtain a white mixed crystal block material; grind the obtained white mixed crystal block material to obtain particles (powder )Material.
[0087] figure 1 for CaF 2 : XRD spectrum of 2% Yb fluorescent cluster material and absorption spectra of samples with different molar ratios. Under the irradiation of 266nm or 915nm ultraviolet light, CaF 2 : 1%Yb fluorescent cluster material can emit near-infrared light near 1μm, such as figure 2 and image 3 shown. The measurement results show that under the irradiation of 355nm ultr...
Embodiment 2
[0089] Ca 1-x Sr x f 2 : Preparation and optical properties of 0.5%Yb(x=0,0.5,1,2,3,5%) fluorescent cluster materials.
[0090] According to Ca 2+ with Sr 2+ The molar ratio of CaF was weighed respectively 2 and SrF 2 , the total amount of the mixture is 2mmol, fully ground to make it evenly mixed; then 0.04mmol YbF 3 Add it to the above mixture and continue to grind. After mixing evenly, put it into a porcelain boat, place it in a vacuum environment at 1200 ° C for 2 hours, and take it out after naturally cooling to room temperature. Under the irradiation of 980nm near-infrared light, 0.02mmol of divalent cation Sr 2+ The cooperative luminescent properties of fluorescent cluster materials such as Figure 9 As shown, it indicates that the material is a Yb fluorescent cluster material with cluster luminescence characteristics. Under the irradiation of 266nm or 355nm ultraviolet light, Ca F 2 : 2%Yb / 1%Sr fluorescent cluster material can emit near-infrared light near 1μ...
Embodiment 3
[0092] (CaF 2 ) 1-x (CaCl 2 ) x : Preparation and optical properties of 0.5%Yb(x=0,1,2,5,7,10%) fluorescent cluster materials. According to CaF 2 with CaCl 2 Weigh a certain amount of CaF in the molar ratio 2 and CaCl 2 , the total amount of the mixture is 2mmol, grind it well to make it evenly mixed. Then 0.01mmol YbF 3 Add it to the above mixture and continue to grind. After mixing evenly, put it into a porcelain boat, place it in a vacuum environment at 1200 ° C for 2 hours, and take it out after naturally cooling to room temperature. Under the irradiation of 980nm near-infrared light, the monovalent anion Cl - The cooperative luminescent properties of fluorescent cluster materials such as Figure 14 As shown, it indicates that the material is a Yb fluorescent cluster material with cluster luminescence characteristics. Under 266nm or 355nm ultraviolet light irradiation, (CaF 2 ) 1-x (CaCl 2 ) x :0.5%Yb(x=0,1,2,5,7,10%) fluorescent cluster materials can emit n...
