YAG Lake Blue Lab Grown Yttrium Aluminium Gemstone Garnet Cut Gems For Decoration Earring Necklace
Yttrium aluminum garnet (YAG) is a synthetic crystalline material with the formula Y3Al5O12 and a cubic crystalline structure. Because of its excellent physical and chemical properties, it is widely used in many industries. YAG has a hardness of between 8 and 8.5, a density of 4.55 g/cm³, a refractive index of 1.833, and high thermal stability, high hardness, and good chemical heat resistance.
In the jewelry industry, YAG has been used as a substitute for diamonds and other precious stones. It comes in a variety of color variants, including green (chromium-doped), blue (cobalt-doped), red (manganese-doped), etc. These colors are achieved by adding different elements. As a synthetic gemstone, YAG is valued for its transparency, durability and high refractive index. It has a critical Angle of 33 degrees, is cut in a manner similar to natural garnet, and is usually polished using alumina or diamond.
YAG also has important applications in the field of laser technology. For example, neodymium-doped YAG (Nd:YAG) lasers are one of the most commonly used active laser media in solid-state lasers and are widely used in medical, industrial cutting and other fields. YAG is also used for scintillators in radiation detection, signal amplifiers in optical communication systems, and lighting.
Features
Other key properties of YAG crystals include:
1. YAG (Yttrium aluminum garnet) is a synthetic gemstone material with a chemical composition of Y3Al5O12, which belongs to the garnet group of synthetic crystalline materials. This material is widely used in optical devices and laser technology due to its high hardness, chemical resistance and heat resistance.
2. In the field of gemstones, YAG has been used as a substitute for diamonds and other gemstones, especially the green variant. This green YAG is achieved by doping chromium elements with high transparency and dispersion, giving it a natural gemstone-like appearance after cutting.
3. YAG has a hardness of 8-8.5, a density of 4.5-4.6 g/cm³, a refractive index of 1.823, and a glassy luster to subadamantine luster. Its critical Angle is 33 degrees, which means that in optical applications, YAG can be effectively used in laser systems.
4. In addition, YAG also has good thermal conductivity and mechanical properties, making it stable in high temperature environments. In terms of optical properties, YAG has a dispersion rate of 0.104, which makes it have high application value in optical devices.

Applications
1. Laser technology: One of the most popular uses of YAG is in the field of laser technology. YAG crystals are usually doped with neodymium (Nd), resulting in Nd: YAG lasers. These lasers are used in a wide range of applications, from medical procedures to industrial cutting and drilling.
2. Phosphor and lighting: YAG is also used for phosphor and LED lighting. YAG's ability to carry different ions allows it to emit a variety of colors of light when excited, which makes it an excellent material for lighting applications.
3. Scintillator: YAG is used as a scintillator in radiation detection. Use cerium ions (Ce3+) to make them twinkle, or glow, when hit by high-energy radiation. This property allows them to be used in gamma and X-ray detectors.
4. Optical communication: Due to its excellent optical properties, YAG is used in the telecommunications industry. Specifically, erbium-doped YAG crystals are used as signal amplifiers in fiber optic communication systems.
5. Jewelry: Synthetic YAG crystals are used as diamond imitations in jewelry because of their high refractive index and dispersion. While they are not as bright as diamonds, they offer a cost-effective alternative with a similar appearance.
The wide application of YAG attests to its important role in a variety of technical and industrial Settings, making it a material of great interest and research.
