Characteristics of Quality Zno powder 99.7

1. It is a potential short-wavelength luminescent material, which can be applied to visible and ultraviolet emitting materials at room temperature or higher; and the high energy band gap brings high breakdown voltage for zinc oxide, strong ability to maintain electric field, and low electronic noise , The advantages of high bearable power;

2. High exciton binding energy: much higher than the thermal ionization energy at room temperature, the stimulated emission of excitons can be achieved at 550K 3 times that of ZNSE and GaN materials, allowing excitons to recombine at high temperatures. This makes the optical phenomena of Quality Zno powder 99.7 at room temperature mostly exhibit excitonic behavior. Quality Zno powder 99.7 has higher luminous efficiency and lower energy consumption, making it an ideal material for light-emitting devices.

3. Strict crystallographic polarity: so it is also a piezoelectric material with excellent performance

4. Quality Zno powder 99.7 has a high melting point of 1975℃, strong thermal stability, high breakdown strength and high electron mobility. It is also an ideal material for high-temperature, high-energy, and high-speed electronic devices.
