Abstract

PURPOSE:To improve the service life characteristics and initial luminous flux of a fluorescent lamp, by adding a specified amt. of gadolinium borate to a starting material mixture for a phosphor comprising yttrium oxide or lanthanum oxide activated with europium, and calcining the resulting mixture. CONSTITUTION:In preparation of a red light-emmisive phosphor of general formula: (Ln1-XEUX)2O3 (wherein Ln is at least one of Y and La; and 0.01<=x<=0.2), oxides or compds. capable of being converted into oxides by thermal decomposition are used in the form of a starting material mixture, to which 2.6-8.5wt.% of gadolinium borate is added to prepare a mixture, which is then fired.
