Highly Luminous Hollow Chloroapatite Phosphors Formed by a Template-Free Aerosol Route for Solid-State Lighting

Abstract

Highly luminous hollow chloroapatite blue phosphors were directly synthesized by an aerosol route. It is noteworthy that the hollow structures of the chloroapatite phosphors were achieved in a rapid manner (within several seconds) without using any templates, which offers tremendous advantages, such as saving time and energy, freedom from contamination, a lowering density, and a reduction of costs for both templates and raw materials. The as-prepared phosphors exhibited extremely high quantum efficiency (QE, as high as 100% under 365 nm excitation), showing great promise for white light-emitting diode (LED) application.

Extraction and characterisation of apatite- and tricalcium phosphate-based materials from cod fish bones

“…FAp is also used as a biomaterial, often mixed with β-TCP [1,8,9]. ClAp is also a very valuable material for different applications; as an example, if doped with appropriate metals such as europium, it can behave as a phosphor [10].…”

White Light Emission from NaCaPO4:Dy3+ Phosphor for Ultraviolet‐Based White Light‐Emitting Diodes

“…R esearch in phosphor materials play a very important role due to their emerging technology such as lamps, plasma display panels, field emission displays, and solid‐state lighting (SSL) 1–4 . SSL in the form of light‐emitting diodes (LEDs) is budding as a highly competent field and is a subject of intense research.…”

Preparation, kinetics of sinter-crystallization and properties of hexagonal strontium-yttrate-silicate apatite phase: SrY4[SiO4]3O

“…Calcium, strontium and barium chloroapatites, where hydroxyl groups are completely substituted by chlorine, can be used in electronics as phosphor material, due to its fluorescence [14][15][16][17]. The synthesis, the crystal structure and the magnetic properties of Sr 5 (CrO 4 ) 3 (Cu 0.586 O) with apatite-like structure were reported by Tyutyunnik and Bazuev [18].…”
