摘要
We report what we believe to be an innovative method for the homogeneous distribution of phosphor particles inside the optical resin-based layer using a vertical vibrational technique for efficient laser-based white light illumination. In this method, single-stage vibration energy was efficiently used against phosphor sedimentation with the help of a mechanical vibrator system. The vertical vibrational energy was transferred to negate the downward gravitational effect acting on each phosphor particle. Therefore, the phosphor particles inside the layer were stable and uniformly distributed from the initial to final drying stages, creating approximate refractive index homogeneity inside the medium. The sedimentation problem was resolved, and all the optical parameters to support this method were properly analyzed and found to be stable and suitable for laser-based illumination applications.
