ChemInform Abstract: Ca[LiAl₃N₄]:Eu²⁺ — A Narrow‐Band Red‐Emitting Nitridolithoaluminate.

Abstract

Ca[LiAl3N4]:Eu2+ is prepared by firing a mixture of Ca, LiAlH4, LiN3, AlF3, and 5 mol% EuF3 (Ta ampules, 1000 °C, 4.5 h).

Narrow-Band Green-Emitting Phosphor Ba2LiSi7AlN12:Eu2+ with High Thermal Stability Discovered by a Single Particle Diagnosis Approach

“…Recently, a new red phosphor was reported, and it has attracted much attention due to its narrow-band-emitting spectrum which makes it suited to several applications. [5][6][7] A new green phosphor is also a type of required phosphor, as well as the red phosphor.…”

“…One is to investigate known crystal structures that are suitable for luminescent center doping and are not studied to be host crystals. [1][2][3][4] The other is to find new host materials by analyzing single crystals [5][6][7]11,[13][14][15][16][17][18] or powder products 12,19,20 . In the single crystal analysis, a large-size crystal (typically larger than 100 μm in all dimensions) is necessary to determine the crystal structure.…”
