<P>PROBLEM TO BE SOLVED: To provide a film using a complex which is cheaper than complexes of platinum group metals, and is excellent in durability in the presence of oxygen as a light emission material. <P>SOLUTION: The film contains a silver complex represented by the composition formula (1): (Ag<SP POS="POST">+</SP>)(L<SP POS="POST">1</SP>)<SB POS="POST">a</SB>(L<SP POS="POST">2</SP>)<SB POS="POST">b</SB>(L<SP POS="POST">3</SP>)<SB POS="POST">c</SB>(X<SP POS="POST">1</SP>)<SB POS="POST">d</SB>(wherein L<SP POS="POST">1</SP>is a molecule having ≥3 and ≤6 of the total number of one or more phosphorus atoms, and one or more selected from a nitrogen atom, an oxygen atom, a sulfur atom, an arsenic atom, an oxygen anion and a sulfur anion; L<SP POS="POST">2</SP>is a molecule having two of the total number of atoms and ions selected from the atoms and ions described above; L<SP POS="POST">3</SP>is a molecule having one atom or ion described above; X<SP POS="POST">1</SP>is an anion; and a is a number larger than 0.5, and b, c and d are each independently a number equal to or larger than 0). A light emission device uses the film. <P>COPYRIGHT: (C)2012,JPO&INPIT |
