<p><P>PROBLEM TO BE SOLVED: To provide a wavelength conversion filter which has high light resistance and can emit fluorescent light at high intensity by converting the absorbed wavelength. <P>SOLUTION: The wavelength conversion filter has wavelength conversion capability including at least one kind of trimethine cyanine compound expressed by formula (I). In the formula, R1-R17 respectively indicate a hydrogen atom, a halogen atom, a nitro group, cyano group, aldehyde group, carboxyl group, hydroxyl group, -NRR', 1-20C alkyl group which may be substituted, 6-20C aryl group which may be substituted, and 7-20C arylalkyl group which may be substituted, and R and R' independently indicate hydrogen atom, 1-20C alkyl group which may be substituted, or 6-20C aryl group which may be substituted. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
