Adamantane-Type Nitridophosphate Phosphors AELiPN : Eu2 via Medium-Pressure Ion-Exchange Reactions.

Nitridophosphates have emerged as promising host compounds in the field of solid-state lighting. Their industrial relevance has increased significantly, mainly due to recent advances in synthetic approaches under medium-pressure (MP) conditions, including ammonothermal synthesis and hot isostatic pressing (HIP). In this study, we report on the synthesis and characterization of the quaternary representatives CaLiPN (x=2, 2.

Scalable Bulk Synthesis of Phase-Pure γ-SnN as a Model for an Argon-Flow-Mediated Metathesis Reaction.

Nitrides represent a promising class of materials for a variety of applications. However, bulk synthesis remains a challenging task due to the stability of the N molecule. In this study, we introduce a simple and scalable approach for synthesizing nitride bulk materials.

Ammonothermal Synthesis of Luminescent Imidonitridophosphate BaPN(NH):Eu.

The structural variability of a compound class is an important criterion for the research into phosphor host lattices for phosphor-converted light-emitting diodes (pc-LEDs). Especially, nitridophosphates and the related class of imidonitridophosphates are promising candidates. Recently, the ammonothermal approach has opened a systematic access to this substance class with larger sample quantities.

ZnHPN: Case Study on Topochemical Imidonitridophosphate High-Pressure Synthesis.

Nitridophosphates are subject of current research, as they have a broad spectrum of properties and potential applications, such as ion conductors or luminescent materials. Yet, the subclass of imidonitridophosphates has been studied less extensively. The primary reason is that the controlled N-H functionalization of nitridophosphates is not straight forward, making targeted synthesis more challenging.

CaLiPN - A Quaternary Chain-Type Nitridophosphate by Medium-Pressure Synthesis.

Nitridophosphates are in the focus of current research interest due to their structural versatility and properties, such as ion conductivity, ultra-incompressibility and luminescent properties when doped with suitable activator ions. Multinary representatives often require thorough investigation due to the competition with the thermodynamically more stable binary and ternary compounds. Another point of concern is the synthetic control of structural details, which is usually limited by conventional bottom-up syntheses.

Trigonal Planar [PN] Anion in the Nitridophosphate Oxide Ba[PN]O.

Nitridophosphates, with their primary structural motif of isolated or condensed PN tetrahedra, meet many requirements for high performance materials. Their properties are associated with their structural diversity, which is mainly limited by this specific building block. Herein, we present the alkaline earth metal nitridophosphate oxide Ba[PN]O featuring a trigonal planar [PN] anion.

Tunable Narrow-Band Cyan-Emission of Eu-doped Nitridomagnesophosphates BaSr[MgPN] : Eu (x=0-3).

Tetrahedron-based nitrides offer a wide range of properties and applications. Highly condensed nitridophosphates are examples of nitrides that exhibit fascinating luminescence properties when doped with Eu, making them appealing for industrial applications. Here, we present the first nitridomagnesophosphate solid solution series BaSr[MgPN] : Eu (x=0-3), synthesized by a high-pressure high-temperature approach using the multianvil technique (3 GPa, 1400 °C).

Multicationic Tetrahedra Networks: Alkaline-Earth-Centered Polyhedra and Non-Condensed AlN-Octahedra in the Imidonitridophosphates AEAlPN(NH) (AE=Ca, Sr, Ba).

A series of isostructural imidonitridophosphates AEAlPN(NH) (AE=Ca, Sr, Ba) was synthesized at high-pressure/high-temperature conditions (1400 °C and 5-9 GPa) from alkaline-earth metal nitrides or azides CaN/Sr(N)/Ba(N) and the binary nitrides AlN and PN. NHF served as a hydrogen source and mineralizing agent. The crystal structures were determined by single-crystal X-ray diffraction and feature a three-dimensional network of vertex-sharing PN-tetrahedra forming diverse-sized rings that are occupied by aluminum and alkaline earth ions.

Nitride Synthesis under High-Pressure, High-Temperature Conditions: Unprecedented Insight into the Reaction.

High-pressure, high-temperature (HP/HT) syntheses are essential for modern high-performance materials. Phosphorus nitride, nitridophosphate, and more generally nitride syntheses benefit greatly from HP/HT conditions. In this contribution, we present the first systematic investigation of a nitridophosphate HP/HT synthesis using the reaction of zinc nitride ZnN and phosphorus(V) nitride PN to the nitride semiconductor ZnPN as a case study.
