Abstract

A new phosphor material, Y_1-xTb_xCa ₄O(BO₃)₃ (0≤x≤1) film was grown on SiO₂ substrates by the combinatorial pulsed laser deposition (PLD) method, which enabled us to fabricate continuous composition spread film libraries. Photoluminescence (PL) and PL decay were measured for these film libraries to identify the optimum composition as well as to determine the luminescence mechanism. The film libraries showed strong dependence of luminescence intensities on the chemical composition of Tb ion. The optimum concentration of Tb ions in Y_1-xTb_xCa₄O(BO ₃)₃ was experimentally and theoretically determined to be x=0.2-0.3.
