Intense red emission on dilute Mn-doped CaYAlO4-based ceramics obtained by laser floating zone

Laser Floating Zone Growth: Overview, Singular Materials, Broad Applications, and Future Perspectives

“…Moreover, the increasing interest of industry on efficient optical processes required an updated revision from that reported by Rudolph and Fukuda in 1999 [8]. Indeed, it is remarkable the great interest that has arisen recently on crystals for ultrashort pulsed laser systems [50,51] and for LED devices applied for indoor plants' growth [52], as a consequence of the increasing food requirements derived from the human population increase.…”

“…Additionally, due to their optical properties and their efficiency, it is also interesting to remark on the works focused on the growth of laser garnets based on disordered crystals like sesquioxides, fluorides, or chalcogenides (Table 4 (LSO) suitable to be used as scintillators have been grown in the last decade by this technique [111,112]. Visible light emission, highly efficient, solid-state, light-emitting materials allowing the fabrication of devices with low energy consumption, high brightness, and environmentally friendly characteristics, are presently of great interest for many researchers [52]. Thus, the LFZ or LHPG technique has allowed obtaining a wide production of phosphors and luminescent materials in the form of doped single crystals or polycrystalline and eutectic materials [52,73,74,[112][113][114][115] in a fast manner.…”

Despite this vast production, considering that this section is focused on single crystals applied as laser media or other specific optical engineering applications, we will not delve into a topic that would probably need a chapter by itself.…”
