The objective of this paper is to review the use thermoluminescence (TL) and optically stimulated luminescence (OSL) techniques as research tools in luminescence, particularly detect presence trapping centers that can degrade efficiency scintillators, shape properties persistent phosphors, storage phosphors dosimeters. A brief main analysis provided, followed by a discussion their limitations. ...

This paper reviews the state of phosphor thermometry, focusing on developments in the past 15 years. The fundamental principles and theory are presented, and the various spectral and temporal modes, including the lifetime decay, rise time and intensity ratio, are discussed. The entire phosphor measurement system, including relative advantages to conventional methods, choice of phosphors, bondin...

Phosphors that offer considerable performance as well heat consistency has been a high priority of recent studies concerning light-emitting diodes (LED) devices. This study employs the perovskite phosphors BCSOF (short for Ba<sub>1-x</sub>Ca<sub>x</sub>ScO<sub>2</sub>F:0.001Bi3+,0.001K+ with x value from 0 to 0.12 and one chip at 415 nm generating thin green ...

Adv. Mater. 2009, 21, 1–5 2009 WILEY-VCH Verlag Gmb We demonstrate print-deposition of high resolution, patterned, multicolored thin films of luminescent colloidal quantum dot (QD)-polymer composites and use the printed patterns in fabricating robust, bright, full-color AC-driven displays. The benefits of AC electroluminescent (EL) displays include simple, low-cost fabrication and high reliabil...
