A method of manufacturing a chiral nano-structure having chirality using a magnetic field according to one embodiment of the present disclosure includes a magnetic field forming operation that forms a magnetic field; a particle arranging operation that arranges at least two nanoparticles in the magnetic field; and a magnetic field adjusting operation that adjusts at least one of a magnetic flux density, a magnetization direction, and a spatial range of the magnetic field, in which in the magnetic field adjusting operation, the arrangement of the nanoparticles arranged in the magnetic field is aligned to correspond to a structure of the magnetic field, and the entire structure is formed as a nano-structure having chirality.

As a magnetoplasmonic particle that can have physical reactability, that is, arrangement variability to a magnetic field to implement an immediate self-assembly property, can be manufactured as a three-dimensional structure through a significantly simplified process compared to the conventional one based on this arrangement variability due to the application of the magnetic field, can be used in various technical fields because an additional change or adjustment of a geometrical of this three-dimensional structure is easy, there is provided the magnetoplasmonic particle including a core-shell particle including a core and a shell surrounding at least a part of a surface of the core and including a component different from a component of the core, and having the arrangement variability due to the application of the magnetic field.

The radiation detector (10) comprises a scintillator (15) having a first refractive index (n.sub.s) for converting incident radiation (RR) received at a first side (S1) of the radiation detector (10) into converted radiation (CR), a photosensor (20) for receiving the converted radiation (CR) from the scintillator (15), and an optical coating layer (25) arranged between the scintillator (15) and the photosensor (20). The scintillator (15) has regions (RR) arranged for being imaged, when impinged by the incident radiation (RR), onto corresponding regions of the photosensor (20). The optical coating layer (25) has a second refractive index (n.sub.o) lower than the first refractive index (n.sub.s) for reflecting the converted radiation (CR) resulting from the incident radiation (RR) impinged on a particular region (A1) of the scintillator (15) and received by a region (A3) of the optical coating layer (25) corresponding to a photosensor region different from the imaged one (A2).
