摘要
Luminescent lanthanum gallate having the perovskite structure and activated by trivalent Tm. The gallate comprises aluminium and is defined by the formula La1-xTmxGa1-yAlyO3 in which up to 20 mol.% of the lanthanum may be replaced by yttrium, gadolinium, lutetium and/or scandium and in which 10-4 /= x /= 0.05 and 0.20 /= y /= 0.80. Upon cathode ray excitation the gallate has the narrow blue-line emission of Tm3+ and is particularly suitable for use in the luminescent screen of high-load cathode ray tubes, for example projection television tubes.
