From: A novel randomly textured phosphor structure for highly efficient white light-emitting diodes
Wavelength-dependent haze intensity and angular-dependent relative intensity measurements. (a) The measured wavelength-dependent haze intensity with phosphor in flat/textured silicone structures; the inset is the flat/textured silicone structures without phosphor, and (b) measured angular-dependent relative intensity of the flat and textured phosphor structures at a driving current of 120 mA.
