“…These lines are not observed in the excitation and absorption spectra of the Dy 3+ doped samples without Gd 3+ component [26,27]. This implies that energy transfer from Gd 3+ to Dy 3+ ions has occurred in this crystal.…”

Crystal and transparent ceramics have been considered to be a new generation of materials with a very important role in secure and economic sustainable development. In this paper, the advantages and disadvantages among highly crystalline transparent glass ceramics, crystals, and ceramics have been compared, including their chemical composition, preparation technology, and the equipment requirement of the materials. Based on the author's knowledge and understanding, the possibility of highly crystalline transparent glass ceramics substituting for crystals or ceramics has been discussed. The present situation and newest progress in the research of highly crystalline transparent glass ceramics have been introduced. The attractive opportunities and difficult challenges in this research direction are shown in this article. In particular, this paper focuses on some ideas from the author, rather than a simple introduction to the existing situation and research progress of transparent materials.

“…Among different RE 3+ , dysprosium ion (Dy 3+ ) can exhibit primary blue ( 4 F 9/2 → 6 H 15/2 ) and yellow ( 4 F 9/2 → 6 H 13/2 ) emissions. When contained in a suitable host, Dy 3+ ‐doped materials can emit white light by adjusting the accurate intensity ratio of yellow‐to‐blue (Y/B), 19 applied in solid‐state lasers, Q‐Switch devices, and fiber optics telecommunication amplifiers 20–22 . Furthermore, the electric dipole transition 4 F 9/2 → 6 H 13/2 of Dy 3+ strongly depends on the crystal field of the host.…”

By regulating the host environment or Dy 3+ concentration, the Y/B values may be effectively modulated.…”

Compared to common incandescent and fluorescent lamps, solid-state lighting (SSL) has gained tremendous attention owing to their high luminous efficiency, high brightness, low power consumption and long lifetime. 1-4 Lightemitting diodes (LEDs) in SSL sources exhibit widespread applications in backlighting displays, data communications, medical devices, barcode scanners, and signals. 5,6 White light is commonly obtained by the excitation of either ultraviolet (UV) or blue emitting LED chips that encapsulate phosphors in an epoxy resin. However, phosphors coated on the chips are easily deteriorated due to heating, contacting with organic solvents or re-absorption of blue light, reducing the quality of emitted light. 7,8 Meanwhile, phosphors own lower thermal conductivity and higher surface energy than that of bulk counterparts, partly reducing the emission efficiency and lifetime of LEDs. Therefore, it is of great interest to develop bulk materials with the advantages of simple packaging, good thermal stability, and high efficiency of heat conduction for LEDs. Nonetheless, frequently studied bulk luminescent materials are concentrated in glass-ceramics, such as Y 3 Al 5 O 12 (YAG) and the derivatives. 9-11 To expand the functionalities in LEDs, especially WLEDs, it is of significance to explore novel luminescent bulks.
