The blue shift and the change of luminescent intensity can be attributed to the quantum-size-effect of the phosphor particles.
并认为蓝移现象以及余辉衰减变快，主要归因于发光粉体纳米粒子的量子尺寸效应的影响。
Spherical particles have minimum scattering area, high packing density; which is beneficial to the luminescent intensity and lifetime of the devices.
球形颗粒荧光粉的光散射面积最小，堆积密度大，有助于提高发光材料的发光强度和使用寿命。
The coating is environmentally friendly and has longer luminescence afterglow time and higher luminescent intensity than corresponding luminescent powder.
该发光涂料环境友好，而且比相应的发光材料具有更长的余辉发光时间和更高的发光强度。
