Embodiment 1
[0034] 1) Make the size 1×1cm 2 The molybdenum foil was put into acetone, ethanol, and ultrapure water successively as a support base for ultrasonic pretreatment, and the ultrasonic time was 20 minutes each.
[0035] 2) Accurately weigh 10mg Ca 3 (PO4 ) 2 ·6H 2 O. Measure 20mL of ultrapure water and prepare a concentration of 5×10 -4 g / L Ca 3 (PO 4 ) 2 ·6H 2 O solution, put the molybdenum foil obtained in step 1) into the concentration of 5×10 -4 g / L Ca 3 (PO 4 ) 2 ·6H 2 Soak in O solution for 24 hours. After soaking, take out the molybdenum foil, place a small amount of gold wire and zinc source on the molybdenum foil as the growth substrate, and place it on a quartz boat. Weigh a small amount of red phosphorus as the phosphorus source and place it on a quartz boat, put the phosphorus source and the growth substrate together into the quartz tube, and the distance between them is about 10cm.
[0036] 3) In hydrogen and an inert atmosphere of argon, the flow rate ...
Embodiment 2
[0039] 1) Make the size 1×1cm 2 The molybdenum foil was put into acetone, ethanol, and ultrapure water successively as a support base for ultrasonic pretreatment, and the ultrasonic time was 20 minutes each.
[0040] 2) Accurately weigh 15mg Ca 3 (PO 4 ) 2 ·6H 2 O. Measure 20mL of ultrapure water, and prepare a concentration of 7.5×10 -4 g / L Ca 3 (PO 4 ) 2 ·6H 2 O solution, put the molybdenum foil obtained in step 1) into the solution and soak for 24 hours. After soaking, take out the molybdenum foil, place a small amount of gold wire and zinc source on the molybdenum foil as the growth substrate, and place it on a quartz boat. Weigh a small amount of red phosphorus as the phosphorus source and place it on a quartz boat, put the phosphorus source and the growth substrate together into the quartz tube, and the distance between them is about 10cm.
[0041] 3) In hydrogen and inert gas argon, the flow rate of the hydrogen gas is 20 sccm, and the flow rate of the argon g...
Embodiment 3
[0044] 1) Make the size 1×1cm 2 The preferred molybdenum foil with a higher melting point is used as a supporting base and placed in acetone, ethanol, and ultrapure water in sequence for ultrasonic pretreatment, and the ultrasonic time is 20 minutes each.
[0045] 2) Accurately weigh 20mg Ca 3 (PO 4 ) 2 ·6H 2 O. Measure 20mL of ultrapure water, and configure it to obtain a concentration of 1×10 -3 g / L Ca 3 (PO 4 ) 2 ·6H 2 O solution, put the molybdenum foil obtained in step 1) into the solution and soak for 24 hours. After soaking, take out the molybdenum foil, place a small amount of gold wire and zinc source on the molybdenum foil as the growth substrate, and place it on a quartz boat. Weigh a small amount of red phosphorus as the phosphorus source and place it on a quartz boat, put the phosphorus source and the growth substrate together into the quartz tube, and the distance between them is about 10cm.
