Luminescent particle and method of detecting a biological entity using a luminescent 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).
