Abstract: Abstract The series of Tm-doped phosphates Ca9-xZnxLa0.9(PO4)7:0.1Tm3+ for using in phosphor-convertible white LEDs (pc-WLED) with β-Ca3(PO4)2-type structure were synthesized using a standard high temperature route. Intense emission in the blue region of the visible spectrum… read more here.
