摘要

Abstract

Single-phased

high-color-rendering index (CRI) white-light phosphors are emerging as potential phosphor-converted white-light-emitting diodes (WLEDs) and as an alternative to blends of tricolor phosphors. However

it is a challenge to create a high CRI white light from a single-doped activator. Here

we present a high CRI (Ra = 91) white-light phosphor

(PO

)

3-x

(BO

)

Cl: Eu

composed

of Sr

(PO

)

Cl as the beginning member and Sr

(BO

)

Cl as the end member. This work utilized the solid-solution method

and tunable Eu

emission was achieved. Color-tunable Eu

emissions in response to structural variation were observed in Sr

(PO

)

3-x

(BO

)

Cl solid solutions. This was further confirmed using X-ray Rietveld refinement

electron paramagnetic resonance spectroscopy

and in the photoluminescence spectra. The color-tunable emissions included the white light that originated from the combination of the blue emission of Sr

(PO

)

Cl: Eu

and an induced Eu

yellow emission at approximately 550 nm in the solid solution. Importantly

the white-light phosphors showed a greater R9 = 90.2 under excitation at 365 nm. This result has rarely been reported in the literature and is greater than that of (R9 = 14.3) commercial Y

: Ce

-based WLEDs. These findings demonstrate the great potential of Sr

(PO

)

3-x

(BO

)

Cl: 0.04Eu

as a white-light phosphor for near-UV phosphor-converted WLEDs. These results also provide a shortcut for developing a high CRI white-light phosphor from a single Eu

-doped compound.
