Special Issue Information

Dear Colleagues,

Laser crystals play a crucial role in the development of high-performance lasers for various applications in industry, medicine, and research. As crucial functional materials, crystals come in many forms, such as laser crystals, nonlinear optical (NLO) crystals, piezoelectric crystals, and scintillation crystals. In the last few decades, numerous crystals, for example Nd3+ Y3Al5O12 (YAG), KTiOPO4 (KTP), KH2PO4 (KDP), and LiNbO3 (LN), have been developed and applied as laser and NLO materials.

The purpose of this Special Issue of Crystals dedicated to laser crystals is to collect papers giving an overview of the state of the art of laser crystals or reporting on recent advances in the study of laser crystals including, but not limited to, the topics mentioned below in the keyword list. Scientists and engineers working in the fields of laser crystals and their applications are cordially invited to contribute to this Special Issue.

  • Growth and characterization of laser crystals;
  • Formation and related mechanisms of laser crystals;
  • Properties of crystal materials;
  • Preparation of nanocrystalline materials;
  • X-ray photoelectron spectroscopy studies;
  • Microstructure and morphology;
  • Relationship between structure and properties;
  • New approaches for enhancing laser performance and efficiency.

This study reviews the advanced anti-counterfeiting applications of CsCdCl3, a lead-free all-inorganic perovskite crystal exhibiting dynamic luminescent properties responsive to temperature and UV light. Using synthesis methods such as Bridgman and hydrothermal techniques and incorporating dopants like bromine and tellurium, this research achieves improved luminescent stability, spectral diversity, and afterglow characteristics in CsCdCl3. The crystal demonstrates extended afterglow, photochromic shifts, and temperature-sensitive luminescence, enabling applications in 4D encoding for secure data encryption and in cold-chain temperature monitoring for pharmaceuticals. Despite these promising attributes, the challenges related to photostability, batch consistency, and environmental resilience persist, necessitating further exploration into the optimized synthesis and doping strategies to enhance material stability. These findings underscore the potential of CsCdCl3 for high-security information storage, pharmaceutical anti-counterfeiting, and real-time environmental sensing, positioning it as a valuable material for the next generation of secure, intelligent packaging solutions.
