Up-conversion luminescent materials under the excitation of the pump light source will absorb the energy of the pump light source and convert the energy into light energy, and its conversion capacity is called luminous efficiency S.25]. Luminous efficiency is one of the reference bases to distinguish the quality… Read More »Factors affecting upconversion luminescence efficiency
The study of photochromic compounds as erasable optical storage materials is one of the hotspots in the field of photochromism in recent years. Hershberg was the first to propose that photochromic reactions constitute a memory model that could potentially be used for data storage. Heller et al. summarized… Read More »Optical information storage and photochromic materials
The research of organic photochromic chemistry and materials has been expanding and deepening in recent years. Organic photochromic substances can be roughly divided into the following categories according to their reaction types.
