Disclosed herein is a method of identifying a unidentified substance, comprising directing light from a light emitting source directly upon a stationary unidentified substance; collecting fluorescence from the unidentified substance in a detector; wherein the detector comprises a lock-in detection system; analyzing the fluorescence; and identifying the unidentified substance. Disclosed herein is a detection system comprising a light emitting source; a circuit board; wherein the trigger is operative to trigger a pulse of electrons from the circuit board to the light emitting source; a detector; and a central processing unit, wherein fluorescence generated from an unknown unidentified substance that is illuminated by light from the light emitting source is collected in the detector and analyzed in the central processing unit.

Detector system for unidentified substances

A device for emission of electromagnetic radiation comprises a source of atomic particles and a collector disposed to receive atomic particles from the source. The collector comprises an emission medium, the medium comprising a crystal having a spatial dimension in the range from about 10 nanometers to about 50 micrometers, wherein the emission medium has the capability to generate opposing charge pairs upon absorption of atomic particles from the source and to emit electromagnetic radiation upon recombination of the pairs. The emission may be via spontaneous emission or, in certain embodiments, by stimulated emission. A laser assembly comprising this device, and methods for making the device are also presented herein.
