Hokkaido Univ. Technology：Optical wavelength conversion transparent film：HK25-006
A coated luminous material that absorbs ultraviolet light and emits red light
Complexes composed of the rare earth element Eu (europium) and organic molecules are materials that absorb only ultraviolet light and emit red light with high brightness and color purity, and are being developed for use in displays, lighting, and sensors. Conventional rare earth complexes have low solubility and are prone to crystallization, making them difficult to fabricate transparent molded objects or use as films directly applied to plates, etc. The present invention realizes a transparent, coatable optical wavelength conversion film by mixing a clarifying agent that reduces crystallinity into the rare earth complex. Furthermore, because it absorbs only ultraviolet light and transmits visible light, it can be used in applications such as agricultural films to promote plant growth.
