Abstract: The invention provides a method for providing luminescent particles (100) with a hybrid coating, the method comprising (i) providing a first coating layer (110) onto the luminescent particles (100) by application of a sol-gel coating process, thereby providing coated luminescent particles; and (ii) providing a second coating layer (120) onto the coated luminescent particles by application of an atomic layer deposition process. The invention also provides luminescent particles (100) comprise a luminescent core (102), a first coating layer (110) having a first coating layer thickness (d1) in the range of 50-300 nm, and a second coating layer (120) having a second coating layer thickness (d2) in the range of 5-250 nm.
