You must know that when it comes to radiance, you know that people will say: It is almost inseparable from rare earth! Because rare earths will shine! What do you ask about rare earth luminescent materials? According to experts, rare earth compounds have three major dings: light, electricity and magnetism. Among them, luminescence is the most prominent ding among these three dings. That is to say, the rare earth luminescent material is a rare earth dingal material, which is a…

Rare earth is the general term for 17 rare earth elements, that is, 15 lanthanides + lanthanum and cerium. So, do you know that luminescence is one of the characteristics of rare earth elements? Some experts have shown that under the excitation of light, strontium (Tb3+) emits green light with a wavelength of 545 nm; and erbium (Eu3+) emits red light with a wavelength of 613 nm. Therefore, the rare earth will emit light is valid! However, rare earths are…
