Rare earth targets are made of rare earth elements and alloys and play an indispensable role in modern high-tech fields. With the rapid development of thin film preparation technologies such as physical vapor deposition (PVD) and chemical vapor deposition (CVD), rare earth targets have shown great application potential in many key fields with their unique physical and chemical properties.

Unique properties of rare earth targets

Rare earth elements, including 17 lanthanide elements as well as scandium and yttrium, have excellent physical and chemical properties such as magnetism, light, and electricity due to their unique electronic layer structure. These properties make rare earth targets have high melting points, excellent thermal stability, and special electromagnetic properties, making them ideal for the preparation of high-performance thin film materials. For example, lanthanum targets are often used in the preparation of capacitor films and optoelectronic devices due to their high thermal stability and good electrical conductivity; cerium targets are widely used in automobile exhaust purification catalysts and fuel cell technology due to their excellent chemical stability and catalytic performance.

Application 

‌1. Semiconductor industry‌

In the semiconductor field, rare earth targets are mainly used to prepare high-performance insulating layers, conductive layers and doping materials. Especially in high-k materials and metal gate technology, the application of rare earth targets significantly improves the performance of devices, reduces energy consumption, and provides important support for the advancement of microelectronics technology. For example, rare earth elements such as lanthanum, cerium and neodymium are widely used in the manufacture of advanced integrated circuits, microprocessors and storage devices.

‌2. Optoelectronics field‌

Rare earth targets are also widely used in the optoelectronics field, mainly in the production of light-emitting diodes (LEDs), laser materials and photovoltaic materials. Rare earth elements such as europium and terbium are used to prepare high-brightness and long-life LED light sources due to their unique luminescence properties. In addition, rare earth targets are also used to produce laser materials with specific wavelength laser output, which have important applications in the fields of medical, communication and industrial processing. In the field of solar cells, the application of rare earth elements can improve the efficiency of solar energy conversion and promote the development of photovoltaic technology.

‌3. New Energy Field‌

Rare earth targets also play an important role in the new energy field. In the field of solar cells, rare earth elements such as neodymium and dysprosium are used to produce photovoltaic films for efficient energy conversion, improving the overall efficiency of the battery. For fuel cells, rare earth targets such as yttrium-stabilized zirconia (YSZ) are used to prepare electrolyte materials, which can provide good ionic conductivity at high temperatures and improve the power density and operating efficiency of fuel cells.

‌4. Magnetic Materials‌

In the field of magnetic materials, rare earth alloy targets such as NdFeB are used to produce high-performance permanent magnets, which are key components of modern motors and generators. Rare earth permanent magnet materials are increasingly used in new energy vehicles such as wind power generation, hybrid and electric vehicles, energy-saving home appliances, industrial robots, etc., providing important support for the development of related industries.

Preparation technology of rare earth targets

The preparation technology of rare earth targets mainly includes smelting, electroplating and thermal spraying. Each method has its specific application scenarios and advantages and disadvantages. The smelting method is one of the most commonly used preparation methods. Rare earth elements or their alloys are melted at high temperature and then solidified into targets of the desired shape and size under specific cooling conditions. This method can produce targets with high purity and high uniformity, but the cost is relatively high and the equipment requirements are high. The electroplating method uses electrolysis to deposit rare earth elements or alloys on a conductive substrate. The cost is relatively low and it is suitable for the preparation of targets with complex shapes, but there may be problems with material purity and uniformity. The thermal spraying method is suitable for the rapid preparation of large-area targets. The preparation process is flexible and the thickness and uniformity of the film can be controlled.
