Abstract

Raman scattering and photoluminescence techniques are used to study polystyrene containing TiO₂ (the white dye pigment). It is shown that the spectral features of TiO₂ emission, caused by the vanadium intrinsic impurity in TiO₂, can be used as a luminescent marker that allows the presence of TiO₂ particles in plastic to be determined.

塑料中TiO2颗粒检测的新方法

拉曼散射和光致发光技术被用于研究含有TiO2（白色染料）的聚苯乙烯。结果表明，TiO2发射的光谱特征是由TiO2中固有杂质钒引起的，可以作为发光标记物，用于确定塑料中是否存在TiO2颗粒。
