[0024] The preparation method of the high-efficiency broad-spectrum quantum tailoring luminescent material of the Bi-Nd-Yb co-doped YAG comprises the following steps:
[0025] Step 1, weigh Y according to the molar percentage distribution ratio in the general formula 2 o 3 (A.R.), Al 2 o 3 (A.R.), Bi 2 o 3 (99.9%), Nd 2 o 3 (99.9%), Yb 2 o 3(99.9%), after that, put the weighed drug in an agate mortar and grind it for 1 to 3 hours to mix it evenly, and then put it in a corundum crucible to be sintered;
[0026] Step 2. Put the corundum crucible containing the sample into the tube furnace, evacuate for 1 to 3 times to reduce the pressure in the furnace chamber to below 0.01MPa, and inject argon gas until it is stable, so that the medicine is in the argon gas environment;
[0027] Step 3: Turn on the tube furnace and evenly raise the temperature to 100°C at a rate of 1°C to 5°C per minute and keep it warm for half an hour to remove the remaining moisture in the sample, t...
Embodiment 1
[0035] A kind of Bi-Nd-Yb co-doped YAG powder luminescent material, its composition general formula is Y 3 al 5 o 12 : 0.5mol% Bi 3+ , 0.5mol%Nd 3+ , 5.0mol% Yb 3+ .
[0036] Concrete preparation steps are as follows:
[0037] Step 1, using an electronic balance to accurately weigh yttrium oxide [Y 2 o 3 ] 5.5307g, alumina [Al 2 o 3 ] 4.2559g, bismuth oxide [Bi 2 o 3 ] 0.0388g, neodymium oxide [Nd 2 o 3 ] 0.0281 g, ytterbium oxide [Y 2 o 3 ] 0.3288 g, placed in an agate mortar and ground for 1.5 hours and mixed evenly, then the crude drug powder obtained by grinding was transferred to a corundum crucible for subsequent use; after the mixed drug was ground, the average particle diameter of the mixed drug powder was detected 2 μm; then put it into a 50 mL corundum crucible to be sintered;
[0038] Step 2. Put the corundum crucible containing the raw material powder in step 1 into the tube furnace, and evacuate to a pressure of 0.01MPa in the furnace. After that, ...
