Phosphor with hybrid coating and method of production

A method for providing luminescent particles with a hybrid coating, the luminescent particles comprising a core of a nitride luminescent material and oxide layer at the surface of the core, the method comprising:

• depositing a first coating layer onto the oxide layer of the luminescent particles by application of a sol-gel coating process, thereby providing coated luminescent particles;
• and
• depositing a second coating layer onto the coated luminescent particles by application of an atomic layer deposition (ALD) process, the atomic layer deposition process forming a multilayer comprising alternating layers, the alternating layers comprising a first ALD layer comprising Al2O3 and a second ALD layer comprising a metal oxide selected from a group consisting of Ta2O5, ZrO2, TiO2, Y2O3, Nb2O5, and HfO2.
