In a phosphor according to an aspect, an emission site has a perovskite crystal structure expressed by ABX, in which A and B are each a cation and X is an anion, and an emission element is located at a B site serving as a body center of the perovskite crystal structure.

Phosphor

A phosphor is represented by the general formulaMX&#xb7;MMMO:(Re)where Mis at least one atomic element selected from the group consisting of K, Li, Na, Rb, Cs, Fr, Cu, and Ag, with K being essential; Mis at least one atomic element selected from the group consisting of Mg, Ca, Sr, Ba, Ra, Mn, Zn, Cd, and Sn; Mis at least one atomic element selected from the group consisting of P, V, Nb, Ta, As, Sb, and Bi; X is at least one halogen element, with F being essential; Re is at least one atomic element selected from the group consisting of rare earth elements, with Eu being essential; and a is in the range 0.6&#x2264;a&#x2264;1.4.

A phosphor has the general formula (M,M,M)MOX, wherein Mrepresents at least one element including at least Si and selected from the group consisting of Si, Ge, Ti, Zr, and Sn, Mrepresents at least one element including at least Ca and selected from the group consisting of Ca, Mg, Cd, Co, and Zn, Mrepresents at least one element including at least Sr and selected from the group consisting of Sr, Ra, Ba, and Pb, X represents at least one halogen element, Mrepresents at least one element including at least Euand selected from the group consisting of rare-earth elements and Mn, m is in the range 1&#x2266;m&#x2266;4/3, n is in the range 5&#x2266;n&#x2266;7, and x, y, and z are each in such a range as to satisfy x+y+z=1, 0.45&#x2266;x&#x2266;0.8, 0.05&#x2266;y&#x2266;0.45, and 0.45, and 0.03&#x2266;z&#x2266;0.35.

Phosphor and light-emitting device

A test cell for magnetic immunoreaction assay, comprising a polymer having a quantity of residual magnetism of 15 pT or less, when a magnetic field is applied under a magnetic field of 0.1 T, and with a distance between a sample and a SQUID sensor being set at 1.5 mm, and a method for producing the test cell are provided. A test cell for magnetic immunoreaction assay, comprising a polymer having a metal content of 30 ppb or less, and a method for producing the test cell are also provided. A magnetic signal detected from a magnetic marker to be measured is not buried in or lost to the residual magnetic signal of the test cell itself, but data discrimination can be made clearly.
