A red phosphor for nUV LED based on (Y,Gd)BO3:Eu3+

Improved photoluminescence properties of a new green SrB2O4:Tb3+ phosphor by charge compensation

“…During the past few years, a number of red and green emitting borate phosphors have been synthesized and studied extensively which can be used for fabricating WLEDs [7][8][9][10][11][12][13][14]. However, to the best of our knowledge, there is no report about the green SrB 2 O 4 :Tb 3+ phosphor for potential application on WLEDs.…”

Analysis of Sr2Mg (BO3)2Tb3+ Green Emitting Phosphor for Solid State Lighting: Implication for Light Emitting Diode (LED)

“…One of the lamp brands, namely Philips, has issued products ranging from bulb type lamps, TL lamps (Fluorescent) to the newest Light Emitting Diode (LED) type. While the lamps that are currently most widely used are TL lamps, in addition to the relatively affordable price for the lower middle class, this type of lamp is an Energy Saving Lamp (ESL) because its main working principle is to use gas to produce light, namely fluorescent gas, where it has a cooling effect which reduces heat dissipation [2]. For the type of TL (Fluorescent) there are at least three forms, namely spiral shape, 3U form, and 2U form.…”

The effects of charge compensation on photoluminescence properties of a new green‐emitting ZnB2O4:Tb3+ phosphor

“…Alkaline earth borates doped with trivalent rare earth ions as phosphors for WLED have attracted much attention because of several advantages such as low synthetic temperature, high stability, high luminescence efficiency and low cost of raw materials. During the past few years, a number of red and green borate phosphors have been synthesized and studied extensively, which can be used for fabricating WLEDs . However, it can result in charge imbalance and form charge defects in host lattice when the trivalent rare earth ions replace the divalent alkaline earth ions.…”
