Photoluminescence properties and energy transfer of novel red phosphor Sr3P4O13:Eu3+, Bi3+

Novel Eu3+-activated Ba2Y5B5O17 red-emitting phosphors for white LEDs: high color purity, high quantum efficiency and excellent thermal stability

“…Furthermore, the Eu 3+ ion is expected to be one of the most hopeful species that offers optical devices in the red color region and numerous investigations have been executed in different host materials such as silicates 25 and phosphates 26,27 for the WLEDs application.…”

Synthesis and characterization of Ca3Lu(GaO)3(BO3)4:Ce3+,Tb3+ phosphors: tunable-color emissions, energy transfer, and thermal stability

“…[1][2][3][4] In the lighting industry, white light-emitting diodes (w-LEDs) have many advantages in lighting applications, such as having long working lifetimes and high luminous efficiency, and being energy-saving and environment-friendly, which meet the requirements of saving energy and protecting the environment. [5][6][7][8][9][10] At present, two methods have been used to fabricate the w-LEDs; one is combining a blue InGaN chip with commercial yellow phosphor Y 3 Al 5 O 12 :Ce 3+ , and the other is using an ultraviolet/near ultraviolet (n-UV; 350-420 nm) LED chip and tricolor (red, green, and blue) phosphors. [11][12][13][14][15][16] The former one suffers from low color rendering index and high correlated color temperature, while the latter one has the drawback of adjusting the proportion of the tricolor phosphors in particular applications.…”

Tunable emission from LiBaBO3:Eu3+;Bi3+ phosphor for solid‐state lighting

“…Recently, solid‐state lighting based on white light‐emitting diodes (wLEDs) has become a prevailing trend in illumination technology due to the significant advantages of wLEDs, for example, high luminous efficiency, low energy consumption, long lifetime and being environmental friendliness. Therefore, there is great potential for wLEDs to be considered as next‐generation light sources . To date, wLEDs have been used widely as next‐generation solid‐state lighting (SSL) in many fields such as traffic signals, mobile phones, and residential and industrial lighting .…”
