Luminescent particle and method of detecting a biological entity using a lumiscent particle

The invention provides a luminescent particle ( 10 ) and a method of detecting a biological entity using a luminescent particle, the luminescent particle comprising a core area ( 20 ) and a shell area ( 30 ), the core area ( 20 ) being covered by the shell area ( 30 ), the core area ( 20 ) conferring a luminescent behavior on the luminescent particle ( 10 ) for at least one excitation wavelength and for at least one emission wavelength by means of a nanocrystal material ( 21 ), and the shell area ( 30 ) being provided such that it realizes an antireflective coating ( 31 ) of the core area ( 20 ).
