Structure, photoluminescence and thermal properties of Ce³⁺, Mn²⁺ co-doped phosphosilicate Sr₇La₃[(PO₄)_2.5(SiO₄)₃(BO₄)_0.5](BO₂) emission-tunable phosphor

Abstract

A single phase emission-tunable Sr7La3[(PO4)2.5(SiO4)3(BO4)0.5](BO2):Ce3+,Mn2+ phosphor was synthesized and the photoluminescence, energy-transfer mechanism and thermal properties were investigated.

Temperature‐Sensitive Photoluminescence Property and Energy Transfer Mechanism in the Silicate Phosphor MgY4Si3O13: Eu3+

“…At present, among the large number of photoluminescence materials available, rare‐earth‐doped silicate phosphors are well‐known for their high efficiency and good chemical stability . Apatite silicate MgY 4 Si 3 O 13 (MYSO) was first reported by Suwa et al.…”

“…At present, among the large number of photoluminescence materials available, rare-earth-doped silicate phosphors are well-known for their high efficiency and good chemical stability. [6][7][8][9][10][11][12] Apatite silicate MgY 4 Si 3 O 13 (MYSO) was first reported by Suwa et al in 1968. 13 In this structure, there are two kinds of cationic site, that is, the ninefold coordinated 4f sites with C 3 point symmetry and sevenfold coordinated 6 h sites with C s point symmetry.…”

CaGdAlO4:Tb3+/Eu3+as promising phosphors for full-color field emission displays

“…[18][19][20] Moreover, energy transfer between RE ions should not be ignored in the color tuning of single phased phosphors from theoretical and practical point of view. [21][22][23][24][25][26] In general, Tb 3+ is a widely used activator in phosphors, as its emission is mainly due to the transitions of 5 D 3 / 7 F J in the blue region and 5 D 4 / 7 F J in the green region (J ¼ 6, 5, 4, 3, 2) depending on its different doping concentrations. [27][28][29] With the Tb 3+ concentration increasing, the cross relaxation between the 5 D 3 and 5 D 4 energy level occurs owing to the interaction of the Tb 3+ ions, which enhances the transitions of 5 D 4 / 7 F J with a dominant green emission.…”

Luminescence Mechanism and Thermal Stabilities of a White Silicate Phosphor for Multifunctional Applications

“…In the past several decades, lanthanide‐doped inorganic luminescent phosphors have undergone rapid development on account of their wide range of applications, such as light‐emitting diodes (LEDs), vacuum fluorescent displays, cathode ray tubes, fluorescent lamps, plasma display panels, X‐ray imaging scintillators, infrared quantum counter detectors, field‐emission displays (FEDs), etc . Having many advantages, e.g., high efficiency, low cost, long lifetime, and environmental friendliness, these phosphors, such as silicates, phosphates, and borates, have attracted extensive attention worldwide . Generally, two or more phosphors are intermingled to meet the demands of white light emission in the practical applications.…”

“…[1][2][3][4][5][6][7][8] Having many advantages, eg, high efficiency, low cost, long lifetime, and environmental friendliness, these phosphors, such as silicates, phosphates, and borates, have attracted extensive attention worldwide. [9][10][11][12][13] Generally, two or more phosphors are intermingled to meet the demands of white light emission in the practical applications. However, the multiphosphors experience different light output degradation rates, leading to the unstable white light, and a tradeoff in luminous efficiency attributed to reabsorption.…”
