Optical material |
摘要 |
The optical material in accordance with the present invention contains a specific phosphonate monoester compound such as monoethyl 3-methoxy butyl phosphonate, and a metal ion such as a copper ion or rare-earth metal ion. They may be contained in a solvent or resin. The use of such a specific phosphonate monoester compound improves the compatibility with a resin, whereby the metal ion can favorably be dispersed into the resin. Consequently, spectral characteristics can be improved when the optical member is formed into a resin-made optical member.
