FIELD: physics.
SUBSTANCE: light-emitting device (1) has a light-emitting diode (2) placed on a mounting substrate (3), said device having a lateral peripheral surface (6) and a top surface (8), and an optically active coating layer (7). Said coating layer (7) covers at least a part of said peripheral surface (6), extending from the mounting substrate (3) to said top surface (8), and essentially not covering the top surface (8). At least part of said lateral peripheral surface is pretreated to become either polar or non-polar. The coating composition used to form at least part of said coating layer is either polar or non-polar. Also disclosed are a method of making said device and an array of light-emitting devices consisting of said light-emitting devices.
EFFECT: reducing loss of efficiency due to scattering of light through lateral surfaces of the light-emitting device.
