Recent development in rare earth doped phosphors for white light emitting diodes

Luminescent properties and energy transfer mechanism of NaGd(MoO4)2:Sm3+, Eu3+ phosphors

“…In the research of white LED phosphor, blue and green phosphor are relatively mature but the luminous efficiency, stability and useful life of red phosphor are not satisfactory, which seriously affect the performance and quality of white LED [1][2][3][4][5][6].…”

“…As a result, in the samples of NaGd(MoO 4 ) 2 : 2 mol% Sm 3 þ , X mol% Eu 3 þ (X¼1,3,5,10,20), the R Sm-Eu was calculated to be 21.59, 18.21, 16.28, 13.60, 12.11 and 11.11 Å, respectively. They are listed inTable 1.…”

White‐Light Emission from Dual‐Way Photon Energy Conversion in a Dye‐Encapsulated Metal–Organic Framework

“…[1][2][3][4] Up to now,enormous materials have been developed to possess WLE performance,i ncluding carbon quantum dots, [5] polymers, [6][7][8] perovskites, [9][10][11][12] metalorganic materials, [13][14][15][16][17][18][19][20][21][22] and so on, providing great promise in solid-state lighting (SSL), anticounterfeiting,s ensing and detecting,a nd so on. [1][2][3][4] Up to now,enormous materials have been developed to possess WLE performance,i ncluding carbon quantum dots, [5] polymers, [6][7][8] perovskites, [9][10][11][12] metalorganic materials, [13][14][15][16][17][18][19][20][21][22] and so on, providing great promise in solid-state lighting (SSL), anticounterfeiting,s ensing and detecting,a nd so on.…”

“…White-light-emitting (WLE) materials have attracted continuous attention for their fundamental importance and practical implication. [1][2][3][4] Up to now,enormous materials have been developed to possess WLE performance,i ncluding carbon quantum dots, [5] polymers, [6][7][8] perovskites, [9][10][11][12] metalorganic materials, [13][14][15][16][17][18][19][20][21][22] and so on, providing great promise in solid-state lighting (SSL), anticounterfeiting,s ensing and detecting,a nd so on. In these materials,w hite-light emission is generally produced by aUV-excited one-photon absorption (OPA) process with energy down-conversion.…”

The synthesis and luminescent properties of bonded Eu(III) polymer phosphors for white light‐emitting diode

“…As a new type of solid‐state lighting source, white light‐emitting diodes (LEDs) have the advantages of low energy consumption, small size, long life, high efficiency, environmental protection, and durability and can be applied to various monochrome and color lighting. The organic complexes of lanthanide elements have a variety of structural characteristics, rich energy levels, long luminous life, large Stokes displacement, and wide emission range from ultraviolet (UV) to near infrared .…”
