Zn1 Se1

Zinc selenide (ZnSe) is a binary II-VI semiconductor compound with a zinc blende crystal structure, valued for its wide direct bandgap and optical transparency across the visible and infrared spectrum. It is widely used in optoelectronic devices including blue and green light-emitting diodes (LEDs), laser diodes, and infrared windows for thermal imaging and military applications, where its combination of optical clarity, thermal stability, and radiation hardness outperforms alternatives like gallium arsenide in specific wavelength ranges. ZnSe is also used as a substrate material for epitaxial growth of related semiconductors and in high-power RF applications, making it essential for next-generation photonic systems where broadband transparency and mechanical stability are critical.
